The Crucial $30$ Years: Chiang Kai-shek's Profound Regret and Reflection on Losing Mainland China

This article examines Chiang Kai-shek's deep regret and reflection on the Nationalist Party's (KMT) loss of Mainland China, as documented in his book *Soviet Russia in China*. The article points out that Chiang Kai-shek was a rare leader who frequently engaged in self-examination. He primarily attributed the defeat to the long-term support and infiltration by Soviet Russia to the Chinese Communist Party in terms of finance, weapons, and ideology. His purpose in writing the book was to warn the free world, based on China's bitter lesson, of the Soviet Union's aggressive ambitions masked by a cloak of 'peaceful coexistence.'
