1. What Should Be Verified Before Public Activities Are Confirmed?

Whenever rumors of the North Korean supreme leader's death surface, attention turns to whether he will appear in public again. Yet suspending judgment until a public appearance is confirmed is not enough for experts, research institutions, and the media to fulfill their responsibilities. Other questions need to be asked first. Is the person relaying the information in a position to know the facts? Is there concrete evidence to support the claim? Is the sequence of events described medically and politically plausible, and is it consistent with the information available at the time? In light of past experience, how much credibility do the person's claims deserve? The severe scarcity of information on North Korea does not lend credibility to poorly substantiated claims.

The rumor of Kim Jong-un's death that spread in October 2026 shows why such verification is necessary. Xie Wanjun (謝萬軍), a Chinese dissident living in the United States, claimed that Kim Jong-un had lost consciousness after a cerebral hemorrhage and died while receiving treatment in China, and that his body had been returned to North Korea but his death had not been announced. According to an October 20 report by OhmyNews, he posted the claim on October 18, U.S. local time. Yet while asserting that Kim Jong-un was already dead, the original post did not specify the exact date or time of death.¹⁾

The claim strings together a series of events into a single narrative: the onset of illness and emergency treatment inside North Korea, the involvement of Chinese medical staff, transfer abroad and treatment, death and the return of the body, and the withholding of an announcement. One must therefore ask how the information about each stage was obtained, and whether the alleged events could actually follow one another. Even if North Korea's closed nature makes it difficult to confirm every fact immediately, it is entirely possible to assess the source's access to information, the internal consistency of the claim, and whether supporting evidence exists. Above all, before shifting to others the burden of proving that Kim is not dead, those who claim his death must first present their evidence.

Publicly available material for this verification already existed. On October 20, North Korea reported, with photographs, that Kim Jong-un had visited an exhibition of light-industry clothing and footwear with his family the previous day; this was followed by a statement from Kim Yo-jong and a reply message from Xi Jinping. The provenance, nature, and evidentiary limits of each item must be examined separately. But it is equally unjustifiable to dismiss them without good reason simply because they contradict the rumor. Indeed, even before the October 24 report that Kim Jong-un had led the Conference of Company Commanders, the source of the information, the account of the medical transfer, and the conduct of the North Korean leadership were sufficient to cast serious doubt on the rumor's credibility.²⁾

This article first examines Xie Wanjun's specific claims and his record of spreading false information, and then the flaws in the medical transfer narrative. It goes on to analyze, in turn, the conduct of the North Korean leadership, North Korean practice in announcing a leader's death, Xi Jinping's reply message, and the claim of Chinese military intervention. The aim is not to confirm after the fact, on the basis of Kim Jong-un's subsequent public activities, that the rumor was false. It is to explain why the claim was hard to believe even on the basis of the information available at the time. The October 24 and 25 reports on the Conference of Company Commanders and the visit to Dandong are treated as subsequent material that supports this assessment.

Calling for rigorous verification of the death rumor does not mean denying the health risks facing North Korea's supreme leader or neglecting preparations for his possible death or incapacitation. A distinction must be drawn between a policy judgment, which prepares for future possibilities, and a factual judgment, which accepts that a specific event has already occurred. What this case calls for is a break with the habit of treating North Korea's opacity as grounds for inflating speculation, and the establishment of verification principles that distinguish confirmed facts, unverified claims, and reasonable inferences even when information is limited.

2. Xie Wanjun's Claims and His Record of Repeatedly Spreading False Information

According to press reports, Xie Wanjun's post of October 18 (U.S. local time) opens with the story that Kim Jong-un and Xi Jinping had suffered from the same illness. Kim Jong-un is said to have suffered a sudden cerebral hemorrhage and lost consciousness, and because North Korea's medical conditions made prompt treatment difficult, Pyongyang asked China for help. Peking Union Medical College Hospital reportedly sent a team of medical specialists to North Korea, but because surgical equipment there was inadequate and the patient's condition was critical, Kim was eventually moved to Beijing for surgery, only to die because the window for effective treatment had been missed. The post concludes that his body was returned to North Korea but that the announcement of his death is being withheld.³⁾

This account contains at least six separate events that need to be verified individually: the onset of illness and loss of consciousness, the request to China for assistance, the dispatch of Chinese medical staff to North Korea, the patient's transfer abroad, treatment and death in a Chinese hospital, and the return of the body and the withholding of the announcement. The post does not say who provided the information on any of these stages, or how it was confirmed.

The latter part of the post turns to rumors about Xi Jinping's health. Xie writes, in effect, that the two leaders suffered from the same condition but that Kim Jong-un did not recover. Rather than independently conveying medical information about North Korea's supreme leader, the post grafts the Kim death rumor onto Xie's own claims about Xi Jinping's health and political future.

The post on the medical transfer and death must also be distinguished from the additional claims that accumulated as it spread. An English-language account operated under Xie Wanjun's name (@xie_wanjun) posted claims that 9,000 Chinese troops had been dispatched to Pyongyang to help Kim Ju-ae stabilize the regime, and that the Northern Theater Command of the Chinese People's Liberation Army had raised its alert level. The claim that Kim Yo-jong had seized power was made in a separate post. Medical, succession, and military intervention stories thus circulated together, without even clarifying what power structure a seizure of power by Kim Yo-jong, as opposed to support for Kim Ju-ae, was supposed to imply.

His subsequent claims reveal his mode of reasoning even more clearly. According to reports at the time, Xie cited the fact that Kim Jong-un had not appeared in person to deny the rumor as indirect evidence of his death, and interpreted Kim Yo-jong's warning about loudspeakers aimed at the South as a move to tighten her grip on the military after taking power. In other words, he first assumes the death and then recycles a hardline message toward the South as evidence for that assumption. When photographs were released, it was claimed that they were old; then suspicions of a body double and of AI manipulation began to circulate. Yet the death claim, the photo-recycling claim, and the body-double claim are distinct assertions, each requiring its own evidence.⁴⁾

The first question to ask, then, is whether Xie Wanjun is in a position to know whether Kim Jong-un has died or become incapacitated. Information on the medical condition and security arrangements of North Korea's supreme leader is among the most tightly restricted of all. Anyone who claims he was treated in a Chinese hospital must show a channel of access to that hospital's medical or security personnel or to the relevant authorities. A background in Chinese dissident activism alone does not provide grounds to assume access to information about the North Korean leadership or China's highest-level medical and security apparatus.

Official assessments produced by South Korean or U.S. intelligence agencies through organized collection and analysis should not be given the same weight as social media claims by an individual who does not disclose how he obtained his information. Intelligence agencies typically have multiple means of collection, material from other government bodies, and procedures for cross-checking. Xie Wanjun has presented no such capability or verification process. Describing a specific hospital and a detailed sequence of events does not close this gap.

This is not to say that statements by intelligence officials are always accurate. One must distinguish between an official institutional assessment and personal speculation, and between information obtained firsthand and hearsay passed through several intermediaries. Conversely, an individual with genuine inside contacts and recent firsthand testimony may provide important information. The key criteria are not background or title, but the ability to access the facts in question, the specificity of the material, and whether it has been independently verified. Nothing has been offered to show that the present claims meet these criteria.

Hence the importance of assessing the source's reliability. Among the information circulated through Xie Wanjun's account, at least four cases have been found problematic by independent fact-checks, and the same type of problem appears in the present rumor.

First, in September 2021, Xie posted an image of a newspaper that appeared to claim that the Chinese Communist Party had fought 99% of the invading Japanese army. Annie Lab, a fact-checking project associated with journalism studies at the University of Hong Kong, compared earlier posts with the original Xinhua report and confirmed on October 5 that the original figure was 60% and had been changed to 99% in the circulated image. This was not a difference of historical interpretation; the very headline he presented as the object of his criticism had been altered.⁵⁾

Second, on January 5, 2022, he posted a message to the effect that corrupt officials in Henan Province were resisting arrest by force of arms, accompanied by images resembling a CCTV news broadcast. AFP established that the photos of soldiers and vehicles had been taken not in China but in Mexico in 2008, and that the anchor's image had been lifted from an old broadcast and overlaid with false captions. While AFP noted that the post might have been satire, it explained that some users had taken it as a real event. Regardless of whether there was intent to deceive, the post was a fabrication that could not serve as evidence of armed clashes in China.⁶⁾

Third, on July 24, 2024, Xie circulated an image that appeared to show Xi Jinping being helped out of the Third Plenum of the Chinese Communist Party. On July 31, Radio Free Asia's Asia Fact Check Lab confirmed that it was a satirical composite in which Xi had been substituted into the scene of Hu Jintao's removal from the 2022 Party Congress. The original creator had labeled it as satire and parody and stated that it was not a real scene. Circulating such material as evidence of a leader's ill health or downfall erases the line between creative work and factual reporting. This case, too, shows that Xie did not possess any authentic photograph proving a health problem.⁷⁾

Fourth, on August 18, 2024, he presented as an official announcement of the Chinese Ministry of Foreign Affairs the claim that Xi Jinping was not among the counterparts of Vietnamese leader To Lam during his visit to China. According to the Asia Fact Check Lab, the content came from a personal article posted on the Sohu portal, whereas the ministry's actual announcement explicitly mentioned Xi's invitation and the planned talks. The next day, August 19, media in both countries carried reports and photographs of the meeting. In this case, a personal article was dressed up with the authority of an official announcement, and an incomplete list was used as grounds for claiming the supreme leader's absence.⁸⁾

Fifth, the same problem recurred during the present rumor. On October 21, Xie posted a screenshot of a CNN breaking news report stating that, according to a U.S. source, the North Korean leader was in grave danger after surgery, along with a screenshot of a Japanese Nippon TV report to the same effect, claiming that U.S. intelligence agencies had begun to check the relevant information. These images, however, came from reports aired in April 2020 during an earlier round of rumors about Kim Jong-un's health.⁹⁾ By presenting six-year-old reports as current information, he showed that his past pattern of spreading false information was repeating itself in the present rumor.

Sixth, on the same day, he also posted a broadcast image that appeared to show a female Korean Central Television (KCTV) announcer declaring, "Kim Jong-un has died" (김정은이 사망하셨습니다). North Korean media, however, never refer to the supreme leader by his name alone, but as "the respected Comrade Kim Jong-un," and they describe a supreme leader's death not with the ordinary word samang (사망, "death") but with the reverential term seogeo (서거, "passing"). The image can only be regarded as a fabrication of a broadcast that never existed. Moreover, in this post he gave the cause of death as a "myocardial infarction," contradicting the "cerebral hemorrhage" he had claimed in his first post.

Taken together, these six cases show that Xie Wanjun's account cannot be treated as a verified and reliable channel of inside information. Altered figures, fabricated images, satirical photos, personal articles misrepresented as official announcements, and old broadcast footage appear again and again. His credibility is not being questioned because of his political opposition, but because of a concrete record of failing to distinguish properly between authentic and inauthentic material and to identify its sources. A Human Rights Watch report documents his activities related to the China Democracy Party.¹⁰⁾ But the reality of political activism and the ability to access sensitive medical information are separate matters. While his past errors alone are not grounds for dismissing the present claim, the fact that he once again provided no indication of his sources makes it difficult to believe. When quoting his claims, the media should inform readers of this record and verify them more rigorously than usual.

The problem is not limited to Chinese dissidents. In 2020, Ji Seong-ho, then a lawmaker-elect of the Future Korea Party, claimed to be "99 percent" certain that Kim Jong-un was dead, only to apologize after Kim's activities were made public. The experience of defection is an important asset for understanding North Korean society, but it is no guarantee of access to medical and security information about the current supreme leader. Certainty grounded in one's background must not substitute for a verifiable information network. Nor, however, should one individual's error be used to dismiss the testimony of North Korean defectors as a whole. The same verification standards must be applied person by person and claim by claim.¹¹⁾

3. The Medical Transfer Narrative: Channels of Access and the Absence of Proof

What must first be examined in Xie Wanjun's account of the medical transfer and death is how he obtained and verified the information. He describes the entire process: the onset of illness and loss of consciousness inside North Korea, the request to China for assistance, the dispatch of Peking Union Medical College Hospital staff to North Korea, the transfer to Beijing and surgery, the failed treatment and death, and the return of the body and the withholding of an announcement. Information concerning a supreme leader's medical care, security, and diplomacy involves different institutions and personnel. It cannot be ruled out that some of those involved might have a comprehensive picture of several stages. Yet Xie has not disclosed at which stage his sources were involved, how he distinguished what they witnessed directly from what they heard secondhand, or whether he cross-checked the information through different channels.

The level of detail in the account is therefore not enough to establish its reliability. The problem is not that a single person could not know about multiple stages, but that no evidence has been offered of how the information was obtained and confirmed. The general argument that North Korea is a closed society does not resolve this problem either. On the contrary, the more one emphasizes North Korea's opacity, the greater the poster's responsibility to explain through what special channel he learned of the entire process, from treatment to the transport of the body.

Nor should specificity be mistaken for proof. When the name of the hospital, the illness, the movement of medical staff, the failed surgery, and the return of the body appear one after another, readers may get the impression that separate pieces of information corroborate a single event. But if all of it is the unverified account of one person, there are not several independent pieces of evidence. The claim that Kim died because the critical window for treatment had been missed likewise cannot be assessed without data on the time of onset, initial treatment, transport time, and the timing of surgery; the medical terminology in the post functions less as verifiable clinical information than as a device to lend the story an air of realism. Transferring a patient with a cerebral hemorrhage is not medically impossible, but the more detailed the account becomes, the more items there are to verify and its credibility does not automatically increase.

The account of the transfer itself is also unconvincing. To conclude from the poor medical care available to ordinary North Koreans that even the supreme leader had to be moved abroad immediately is a leap of logic. The supreme leader has a dedicated medical team and separate treatment facilities, and foreign specialists can also be brought in. Indeed, when Kim Jong-il suffered a stroke in 2008, French neurosurgeon François-Xavier Roux treated him in Pyongyang.¹²⁾ Xie cited a shortage of surgical equipment in North Korea and the patient's critical condition as the reasons for the transfer abroad. Yet he did not specify which equipment was lacking, how long the initial treatment and transfer took, or on what basis it was judged that a transfer abroad was preferable to treatment on site. Giving a reason for the transfer is one thing; proving that the explanation is true is another. Nor is there any explanation of the choice of hospital. In light of past reports that Jo Myong-rok was treated at the People's Liberation Army's 301 Hospital in Beijing,¹³⁾ the question remains why, if Kim Jong-un had been moved to China, Peking Union Medical College Hospital would have been chosen over a military medical institution with a record of treating Kim Jong-il and senior North Korean officials. Of course, Peking Union Medical College Hospital is a top-tier general hospital designated by the state to treat severe and complex conditions, so it cannot be ruled out as a possible destination for treatment simply because it is not a military hospital. The key point is that in making such a sensitive claim about medical treatment abroad, Xie offered no evidence whatsoever regarding the choice of hospital or the route of the transfer.

The initial judgment an expert should reach, therefore, is that because the claimant has not presented his channel of access to the information or any independently corroborating evidence, there is no basis for believing this specific account of the death. To state merely that the account cannot be confirmed on the available evidence would obscure the key point that the burden of proof lies with those who raised the death rumor. Placing a baseless claim on the same footing as credible information is not neutrality but an abdication of verification.

4. Could a Death Be Concealed While Normal Rule Is Staged?

The starting point for verification is North Korea's October 20 report on the exhibition visit. The Korean Central News Agency (KCNA) reported that on October 19 Kim Jong-un, accompanied by his daughter Kim Ju-ae and his wife Ri Sol-ju, toured an exhibition of light-industry clothing and footwear held under the theme of "the drive for developing new products and improving quality," and the Rodong Sinmun and other outlets carried several photos of the family examining the exhibits. In a subsequent post, Xie suggested that North Korea had released photos taken while Kim was still alive, but he presented no concrete evidence that the photos had been published before or taken on a different date. At the very least, the claim that old photos had been republished was not proven, and the reports showed entirely new scenes of activity.

Xie's first post went up at 11:14 a.m. on October 19, Korea time, and claimed that by then Kim's death and the return of his body had already taken place. Yet North Korea reported that Kim Jong-un visited the exhibition on that very day, October 19. If, as the rumor holds, Kim Jong-un had died before the exhibition visit, North Korea would have falsely reported that the leader had engaged in public activities after his death. Disclosing the actual date of death later would then contradict the activity reports, while assigning a later date to his death in the official announcement would require aligning the medical account, funeral preparations, and even the records of those involved. One cannot say all this is impossible, but the scope of the cover-up and its political cost grow accordingly. Those who spread the rumor must show why North Korea would bear such costs and provide evidence to that effect.

Ultimately, to sustain the death rumor after North Korea released photos of Kim Jong-un's public activity on October 20, two things had to be proven: first, that the date the photos were taken or the description of the event was false; and second, why North Korea would go out of its way to fabricate an activity report that would conflict with the date of death it would soon have to announce. To point only to the limits of verifying the photos while adopting an interpretation favorable to a death rumor backed by no evidence at all is to treat the evidence asymmetrically.

To judge whether such false activity reports are realistic, North Korea's procedures for the transfer of power must be examined. The death of the supreme leader is not a personal matter but a national event requiring the simultaneous management of command continuity, succession, the funeral and public mobilization, and diplomatic notification. Delaying an announcement for a few days and continuing to present a dead leader as the incumbent by publishing his specific activities carry very different burdens of explanation.

In past cases, North Korea announced the death, published the composition of the state funeral committee, and announced the mourning schedule in quick succession. According to the official announcements, Kim Il-sung died on July 8, 1994, and his death was announced on July 9. Kim Jong-il died on December 17, 2011, and his death was announced on December 19.¹⁴⁾ In both cases, North Korea informed its people one or two days after the death. This should not be regarded as an immutable deadline, but it is clear that the announcement of death is the starting point for formalizing the funeral and the transfer of power.

If, as Xie Wanjun claims, the body had already been returned to North Korea, when and with what date and circumstances of death would the leadership issue an official death announcement? Assuming that the death and the return of the body had already occurred, they would have been followed on October 20 by the report of the October 19 exhibition visit, and on October 21 by Kim Yo-jong and Pak Jong-chon's visit to the border. As time passes, the cover-up theory requires an additional explanation that goes beyond a mere delay in the announcement: that activities and policy implementation continued to be staged after the death.

Keeping a death secret for a short time is qualitatively different from continuing to present a dead person as the ruler. The former may be a way of buying time to prepare the announcement; the latter undermines the very starting point of succession. To formalize the successor's power, the supreme leader's death and the funeral arrangements must be announced, and the organs of the Party, the military, and the state must be given a new basis of authority. Public mourning and pledges of loyalty by officials must also go through public procedures. Conversely, reporting as though the deceased were still conducting on-site guidance and issuing instructions would require falsifying even the record of who is directing the state and under what authority.

The death of a supreme leader is not a private matter that a few family members and aides can conceal. The circle of those involved is wide—medical, security, and secretarial staff, the military command, and the agencies in charge of the funeral—and as time passes, it becomes harder to reconcile the official date of death, the date of the last activity, and the point at which the successor begins to exercise authority. The argument that "North Korea is a closed society, so it can hide anything" fails to account for the institutional and political requirements of a transfer of power. The possibility of a brief delay in announcement must not be stretched into the staging of normal rule for an indefinite period.

Kim Yo-jong and Pak Jong-chon's visit to the border must be read in precisely this context. In her October 21 statement, Kim Yo-jong said that KCNA had misreported the date of the visit and that she had visited several points along the border not the previous day but in the early hours of October 21. The visit should therefore be dated to the early morning of October 21, not October 20. The same statement presented Kim Jong-un's guidelines concerning the border and addressed fortification and military responses toward the South.¹⁵⁾

If the supreme leader had died and funeral preparations were under way, North Korea's core leaders would have had to focus first on how to inform the public and the international community of Kim Jong-un's death, and on who would succeed him and how the transfer of power would be organized. That at such a critical moment Kim Yo-jong visited the southern border with a senior military figure and publicly emphasized implementing policy in line with Kim Jong-un's existing guidelines does not fit well with the explanation that an urgent succession was under way following his death. To treat this move as immediate evidence of Kim Yo-jong's seizure of power is to misinterpret the significance of the visit.

Kim Yo-jong has consistently delivered hardline messages toward the South under Kim Jong-un's rule. Hardline remarks alone therefore cannot prove a new seizure of power, or even distinguish one from the performance of her existing role. To use behavior explainable by her existing role as evidence of a transfer of supreme power, one would need to show what had changed in her position, authority, and chain of command. Kim Yo-jong is a department director of the Central Committee of the Workers' Party of Korea; the fact that she visited the site accompanied by military officials and made remarks about the South does not mean that she has taken over the position of head of state or supreme commander of the armed forces. Implementing policy under the delegated authority of the supreme leader and succeeding to supreme power are entirely different things. Between the observation of a "visit" and the inference of a "seizure of power," the decisive evidence is missing. If every normal activity is labeled a cover-up, no contrary evidence can ever change the judgment.

Xi Jinping's reply message dated October 20 raises an even more fundamental question about the claim of a transfer to China and death there. A death or incapacitation concealed within North Korea is of a completely different order from a case in which North Korea's supreme leader is transferred to China, dies in a Chinese hospital, and has his body returned to North Korea. In the latter case, medical, security, and diplomatic arrangements would be unavoidable, so it is hard to believe that China's top leadership would have been unaware of it. The death in China of the supreme leader of a nuclear-armed neighbor and the return of his body across the border cannot be handled like the admission and discharge of an ordinary patient. Accepting Xie Wanjun's claim of transfer and death therefore requires assuming that the Chinese leadership knew about it. Yet Xi Jinping's reply, released by North Korea on October 22, addresses Kim Jong-un as the incumbent leader and refers to the development of bilateral relations.¹⁶⁾

For the death rumor to hold, then, one must introduce an additional assumption: that Xi Jinping sent a normal diplomatic message despite knowing of Kim's death, and that North Korea made it public. If the death were announced belatedly, the date and content of the reply would raise questions about what the Chinese leadership knew and when, a diplomatic credibility cost that China would have to bear in full. If it came to light that Xi had knowingly sent a reply as if to a living counterpart, Xi himself and China's official communications could hardly avoid criticism for taking part in disinformation. The mere assumption that North Korea needed to buy time does not explain why China's top leader would accept such a burden. If proponents of the death rumor add, without any evidence, a joint cover-up by China, their claim is not proven; it merely piles up assumptions.

The claim that 9,000 Chinese troops entered Pyongyang must be examined separately. Regardless of its cooperation with China, North Korea has consistently been wary of outside interference in its internal power structure. The withdrawal of the Chinese People's Volunteers in 1958 is an important case for understanding the historical background of this relationship.¹⁷⁾ China's general interest in North Korea's stability alone does not justify assuming that the North Korean military would have accepted the entry of foreign troops into the capital and their involvement in the succession. For a North Korea that possesses nuclear forces and makes independence (jajuseong) the core of its claim to legitimacy, the entry of Chinese troops into Pyongyang would raise serious sovereignty concerns, as it could alter responsibility for defending the capital and protecting the regime and undermine the command authority and standing of the Korean People's Army.

Anyone who puts forward a figure as precise as 9,000 troops should also provide corresponding evidence of their movement and deployment. A force of 9,000 troops is of an entirely different order of magnitude from a handful of liaison officers or medical support personnel. Beyond the movement of the troops themselves, it would require vehicles, billeting, food, communications, logistical support, and garrison facilities. Crossing the border and entering Pyongyang would very likely leave traces that could be checked through satellite imagery, transport activity, and on-the-ground observation. It is also hard to imagine a force of this size entering Pyongyang so quickly, as if everything had been prepared in advance. Yet not a single image or eyewitness account identifying the route or the units involved has been presented. The key question is what those who asserted a large-scale deployment have actually presented. The answer that "there is no evidence because it was a secret operation" cannot lend authority to the figure of 9,000 troops or to Pyongyang as their destination.

Seen in this light, sustaining the death rumor requires assuming all at once a medical transfer and the return of the body, the fabrication of activity reports by North Korea, a joint cover-up by the Chinese leadership, and the entry of foreign troops into the capital. Yet there is no evidence for any of these, nor any explanation of how the assumptions fit together. North Korea's closed nature cannot fill all these gaps in the evidence.

5. Beyond After-the-Fact Confirmation: Principles for Verifying Information on North Korea

The October 20 exhibition photos, Kim Yo-jong's October 21 statement, and Xi Jinping's reply released on October 22 are different kinds of material, but all pointed to the continuation of existing rule and policy implementation. Even if none of them explains every aspect of Kim Jong-un's health, they constituted successive refutations of the narrative that he had already died, his body had been returned, and a seizure of power and foreign military intervention were under way. Rather than isolating each piece of material and repeating that "this alone is not conclusive," experts and the media should have assessed which account could explain all the material together.

That the baseless death rumor nevertheless continued to attract attention reveals that South Korean society's system for verifying information on North Korea does not adequately take contrary evidence into account. To be sure, not all media outlets jumped on the bandwagon. OhmyNews had already examined the reliability of the source and the exhibition photos on October 20, and the author's interview on October 22 also pointed out the logical problems of the rumor. The problem is not that there was no verification, but that the verification already available was not sufficiently reflected in subsequent citations and interpretations.

It is also necessary to distinguish between the spread of a rumor and its mutation. According to the Weekly Kyunghyang, messages claiming that Kim Han-sol had been designated as successor and that U.S. Forces Korea would be sent into North Korea were circulating by October 22. These claims were added through a channel different from Xie Wanjun's claim of Chinese military intervention. Past reports that Kim Han-sol had gone into hiding do not prove that he has now been designated successor, and access problems with North Korean websites do not prove the leader's death. Linking events that actually happened to unverified conclusions so that the whole story appears true—this is the core problem.¹⁸⁾

Unverified AI judgments must be held to the same standard. A perceived difference in appearance, or a secondhand claim that a program has identified a body double, is not sufficient to establish that the person shown is not Kim Jong-un. The original images compared, the conditions under which they were taken, the analytical tools and methods, and the potential errors and limitations of the analysis must all be presented. Partial differences in photographs cannot prove death, and adding a body-double theory when death has not been proven does nothing to supply the missing evidence. The media should not use the phrase "AI has confirmed" as a source of authority substituting for expert verification.

In such circumstances, the premise that "North Korea can hide anything" carries more weight than observed facts. A new photo becomes a recycled one, a normal diplomatic message becomes a joint cover-up, and a field visit becomes a sign of a seizure of power. If a new secret is added every time contrary evidence emerges, no claim can ever be judged false. This is not an analysis of North Korea's opacity but a mode of interpretation that makes verification itself impossible.

Judgment on the death rumor was effectively settled by the material that emerged from October 23 onward. First, on October 23, it was reported that the National Intelligence Service (NIS) had informed the National Assembly Intelligence Committee that the death rumor was false.¹⁹⁾

Then, on October 24, the Rodong Sinmun and KCNA reported that Kim Jong-un had led and delivered a speech at the Third Conference of Company Commanders of the Korean People's Army, held in Pyongyang on October 22–23.²⁰⁾ This was a recent act of military leadership that directly contradicts the death rumor.

On the same day, Kim Jong-un visited Dandong, China. That same day, Xinhua published an on-the-ground report, illustrated with photographs taken by its own journalists, describing Wang Huning accompanying Kim, their face-to-face interactions, and visits to commemorative sites. The Rodong Sinmun reported on October 25 on the visit to the memorial hall, the conversation with Wang Huning, a tour of a bus factory, and the return home. Unlike cases in which foreign media simply reprint photos supplied by North Korea, this constitutes strong counterevidence in that activities taking place outside North Korea can be checked against material gathered by Chinese media.²¹⁾

In reports on the Dandong visit, Kim Yo-jong appears, in her capacity as a department director of the Party Central Committee, as one of the officials accompanying Kim Jong-un. This is inconsistent with the claim that she had already seized supreme power in Kim Jong-un's place.

Establishing the facts after the event does not, however, resolve the underlying problem of information verification. To avoid repeating the same confusion when the next death rumor emerges, the following verification principles highlighted by this case should be built into the actual practices of journalism and research.

First, the claimant's access to information should be the starting point for any report or analysis. Credibility must not be determined solely by labels such as Chinese dissident, North Korean defector, former official, or intelligence official. It should be made clear when and through what channel the information was obtained, whether it reflects direct observation or hearsay, and whether it is an institutional assessment or personal speculation. Even when a source cannot be disclosed, the channel through which the information was obtained and the verification process should at least be evaluated in the course of reporting and analysis.

Second, claims should be broken down into individual events, and evidence should be required for each link. Onset of illness, dispatch of medical staff, transfer abroad, death, return of the body, succession, and the entry of foreign troops are not a single fact. Circumstantial evidence for one item must not be stretched into proof of the others. It is useful to seek review from medical experts on the plausibility of emergency treatment and transfer, from North Korean politics specialists on funeral and power-transfer procedures, and from military experts on troop movements and command relationships.

Third, the material available at each point should be compared chronologically. Recording separately the posting date and the alleged date of occurrence, the date of official activity and the date of reporting, and the date of any correction makes contradictions apparent.

Fourth, assumptions added to explain away contrary evidence must themselves be required to have a basis. Reasoning that treats every new photo as recycled, every reply message as a joint cover-up, and the absence of an official response as evidence in itself blocks any possibility of correcting errors. Analysts should state in advance what kind of material would lead them to change their judgment. Nor should they shift the burden of proof that rests on those who claimed the death onto others, arguing that if survival cannot be perfectly proven, death is likely.

Fifth, the media must not present repeated citation as independent confirmation. Even if several foreign media outlets reported the story, if the original source is a single post, the evidence has not increased. The level of verification should be stated in the headline and first sentence, and the source's record of errors and any contrary evidence should be presented together. As further verification clarifies or changes the assessment, changes in judgment should be reflected not only in new articles but also in the original ones. It is also important to distinguish between a simple error in the reported date, deliberate manipulation, and unconfirmed hearsay.

Sixth, the government should explain the basis for its judgments while protecting sources and sensitive movements, and research institutions should distinguish in their analyses between real threats and rumors of the leader's death or incapacitation. There is no need to respond to every rumor, but when the social impact grows, the government can disclose its current assessment to the extent possible. In addition, military tensions in border areas and changes in China-North Korea relations should be analyzed in their own right, rather than treated as side scenes in an unverified narrative of a power vacuum.

Preparing for the possibility of Kim Jong-un's death or incapacitation must be kept strictly separate from amplifying baseless claims that he has already died. Even if North Korea's closed nature makes it difficult to confirm every fact directly, the credibility of a claim can be assessed to a considerable extent by comparing the informant's access to information, the internal logic of the claim, past precedents, and publicly available material from the same period. As this death rumor shows, expertise should be demonstrated not by declaring a story false after Kim Jong-un reappears, but by identifying, before that point, what has not been proven and which explanations conflict with reality.
