Emerging from an award-winning article in International Security, China's Gambit examines when, why, and how China attempts to coerce states over perceived threats to its national security. Since 1990, China has used coercion for territorial disputes and issues related to Taiwan and Tibet, yet China is curiously selective in the timing, target, and tools of coercion. This book offers a new and generalizable cost-balancing theory to explain states' coercion decisions.
