the only legal government of China. In return, the United States would help the Soviet Union persuade the Kuomintang to recognize the legal regime of the Soviet Union in Outer Mongolia. At that time, the relations between the Kuomintang and the Communist Party were very tense, and Chiang Kai-shek always tended to seek help from the United States and the Soviet Union in dealing with the conflict with the Communist Party.
