Which Chinese general signed the 1945 Japanese surrender document on behalf of China?

Hsu Yung-chang signed the 1945 Japanese surrender document on behalf of China.

Hsu, also spelled Xu Yongchang, represented the Republic of China at the surrender ceremony aboard the USS Missouri on September 2, 1945. He signed after Fleet Admiral Chester Nimitz, who represented the United States, and before representatives of the United Kingdom and the Soviet Union.

China had been at war with Japan since 1937, several years before the broader Pacific War began. Japanese forces had occupied large areas of China and committed major wartime atrocities, so China’s presence at the ceremony carried particular political and military significance.

Hsu was a senior Chinese military commander and naval officer in the Nationalist government. The ceremony included representatives from nine Allied governments, but each signed separately for the nation or government represented. This is why the answer is not Chiang Kai-shek, China’s political leader, who did not personally sign the document in Tokyo Bay.
