Abstract: In the months since Donald Trump won the U.S. presidential election in November, policymakers in Beijing have been looking to the next four years of U.S.-Chinese relations with trepidation. Beijing has been expecting the Trump administration to pursue tough policies toward China, potentially escalating the two countries’ trade war, tech war, and confrontation over Taiwan. The prevailing wisdom is that China must prepare for storms ahead in its dealings with the United States. As we approach the symbolic measure of the first 100 days of the second Trump administration, what Trump disruptions are Beijing taking advantage of to advance their own aims? Does the escalating tariff war change that calculus? Bio: Yun Sun is a Senior Fellow and Co-Director of the East Asia Program and Director of the China Program at the Stimson Center.
