This report describes a virtual role-playing peace game exercise conducted in October 2021 that simulated diplomatic negotiations aimed at making tangible progress toward improving relations, enhancing security, and building confidence on the Korean Peninsula. The exercise, hosted by the United States Institute of Peace, Quincy Institute for Responsible Statecraft in Washington, and the Sejong Institute in Seoul, consisted of negotiating teams representing the United States, South Korea, North Korea, and China. 

The U.S. and North Korean teams emerged as the principal actors in the exercise, determining whether negotiations remained static or moved forward. However, these teams perceived potential losses in negotiations more acutely than potential gains, which resulted in diplomatic inertia. Both teams seemed open to negotiations as long as the other side took the first conciliatory step, but presidential leadership and political will were necessary to overcome inaction. The U.S. team also seemed more driven by the risks of North Korean aggression and duplicity in negotiations than the South Korean team, which led to divergent policy approaches between allies. In addition, the U.S.-China rivalry fueled a zero-sum mentality that hindered opportunities for progress and heightened misunderstandings between the U.S. and South Korean teams. These observations lead to the following policy recommendations for the actors involved:  

- Advancing peace and denuclearization will require the highest level of executive leadership and intervention from all parties to build support for a final agreement. For the United States, that means greater presidential prioritization and increased coordination with Congress.

- All parties should start with smaller, more reversible measures; mitigate the risk of failure; and highlight potential gains. The United States should consider confidence-building measures that jump-start negotiations but do not undermine its security interests.

- Washington should strengthen coordination with Seoul on North Korea policy and other key alliance matters to harmonize strategies.

- To achieve progress, all parties should separate issues pertaining to the Korean Peninsula from the U.S.-China contestations.
