Chen Duxiu
In 1920, the Soviet Union established the Far Eastern Bureau in Siberia, a branch of the Third Communist International, or the Comintern. Thus was directly responsible for managing the establishment of a Communist party in China and other far east countries. Soon after its establishment, the bureau's deputy manager Voitinsky arrived in Beijing and contacted the Communist vanguard Li Dazhao. Li arranged for Voitinsky to meet with another Communist leader, Chen Duxiu, in Shanghai. In August 1920, Voitinsky, Chen Duxiu, Li Hanjun, Shen Xuanlu, Yu Xiusong, Shi Cuntong, and others began to establish the Comintern China Branch.
