"The situation in China was full of explosives, the handling of which required delicacy. Shortly before the actual surrender the Japanese withdrew their forces to the Yangtze Valley and to North China, where the Chinese Communists demanded that they receive the Japanese surrender. General Okamura, commander of the North China Area Army, refused, but on 17 August let it be known that he would surrender to Chiang Kai-shek. Unfortunately, the Generalissimo and his Nationalist armies were far distant, in southwest China. A Japanese puppet Chinese government with its own "Peace Preservation Troops" further complicated matters. And although the United States was willing to assist the Nationalist government to reestablish control over Chinese territory, it was fearful of being involved in a civil war."
