"Report No. 217: US-China Reassurance: Theory and Practice" - by CWP alum Kai He

June 05, 2025

The world is currently facing a polycrisis, characterized by overlapping and interconnected global challenges. The ongoing war in Ukraine and escalating military conflicts in the Middle East threaten international stability, while peace and security in the Asia–Pacific region are increasingly at risk due to intensifying US–China strategic competition.

In this increasingly volatile context, a strategic approach is urgently needed to stabilize bilateral relations and prevent military conflicts between the United States and China. This report underscores the necessity of “reassurance” as a conflict prevention measure to address the growing risk of military confrontation and preserve the fragile “East Asian Peace” amid intensifying strategic competition. Reducing the likelihood of conflict between the United States and China is the central research objective of the Toda Peace Institute’s first Research Cluster (TRC) on Northeast Asia. To achieve this objective, this report examines key theoretical and empirical dimensions of US–China reassurance, focusing on the following critical questions:
