Major contents: The congress was held at the critical moment of the Chinese revolution after Chiang Kai-shek staged a counter-revolutionary coup in Shanghai on April 12 of the same year, disarming the workers and having them and Communists rounded up and murdered. It accepted the resolution on the Chinese revolution adopted at the Seventh Enlarged Plenary Meeting of the Communist International Executive Committee. In accordance with the spirit of this resolution, the congress criticized Chen Duxiu for his Right deviationist mistakes as manifested in his neglect in the struggle with the bourgeoisie for leadership over the revolution. But it did not put forward any practical measures for correcting the mistakes so that Chen continued his Right deviationist mistakes after the meeting. The congress set the major tasks for the time being as to launch agrarian revolution and establish the rural revolutionary democratic power, but failed to put forward specific programs to meet the peasants' demand for land. As a result, the congress actually did not finish the task of rescuing the revolution at the crucial moment. It elected the Central Committee composed of 29 members and 10 alternate members.
The Central Committee elected Chen Duxiu, Zhang Guotao, Li Weihan, Cai Hesen, Li Lisan, Qu Qiubai and Tan Pingshan to form the Political Bureau. Chen Duxiu was elected general secretary.
