On this day, 80 years ago, July 29, 1945 (June 21, 1945 in the lunar calendar), Mao Zedong called Foster to congratulate the recovery of the Communist Party of the United States. On July 29, 1945, Mao Zedong called Foster and the Central Committee of the Communist Party of America. Foster called Mao Zedong on the 24th to inform him that the American Communist Political Association would hold a special meeting in New York to correct Browd's revisionist line, adopt a Marxist approach, and rebuild the Communist Party of the United States. He was deeply proud to receive the telegram congratulatory message. From the 26th to the 28th, a special session of the Communist Party of the United States rebuilt the Communist Party and elected a new central leader headed by Foster. In his telegram, Mao Zedong warmly congratulated the Communist Party of the United States for abandoning Browd's revisionist line, rebuilding Marxist leadership, and restoring the Communist Party of the United States. The victory of the American working class and its vanguard will undoubtedly make a major contribution to the current anti-Japanese war and the construction of peace and democracy after the war.
