Page "History of the Republic of China" Paragraph 70

The wartime policy of the United States was initially to help China become a strong ally and a stabilizing force in postwar East Asia.

As the conflict between the Kuomintang and the Communists intensified, however, the United States sought unsuccessfully to reconcile the rival forces for a more effective anti-Japanese war effort.

According to the Potsdam Declaration, the transfer of sovereignty over Taiwan from Japan to the Republic of China occurred on 25 October 1945 ( Retrocession Day ).

Toward the end of the war, United States Marines were used to hold Beiping ( Beijing ) and Tianjin against a possible Soviet incursion, and logistic support was given to Kuomintang forces in north and northeast China.
