When the Japanese surrender on September 2, 1945, there are 25,000 to 30,000 Jews in China, 17,000 of them in Shanghai. The Shanghai ghetto is only opened with the arrival of an American goodwill mission on September 3, 1945. Communists and Nationalists race to establish positions in Japanese-occupied areas of China. During 1945-1947, Manchuria is under Soviet occupation, and Jewish community leaders of Harbin are arrested and sent to the Soviet interior. Chinese Nationalists and Communists sign a truce on January 10, 1946.
