Sun Yat-sen presided over the First National Congress of the KMT held in Guangzhou. The congress adopted an anti-imperialist and anti- feudal declaration drafted with the help of Communists, and decided on the Three Great Policies-alliance with Russia, cooperation with the Communist Party and assistance to the peasants and workers, thus developing the old Three People's Principles into the new Three People's Principles. The congress elected ten Communists, including Li Dazhao, Tan Pingshan, Mao Zedong, Lin Boqu and Qu Qiubai, as members or alternate members of the Central Executive Committee of the KMT. The headquarters of the KMT was also reorganized with Communists serving as director of the Organization Department and the Department of Peasants. The Department of Workers was actually led by Communists, too. Afterwards, most of the KMT local branches throughout the country were reorganized or set up with Communists or KMT Left-wingers comprising the backbone.

The Communist International convened its Fifth Congress. Li Da-zhao, Wang Hebo, Peng Shuzhi and Liu Qingyang attended the congress as representatives of the CPC. The congress stressed the importance of the united front in the colonial countries and the need for the Communist Parties to maintain absolute and complete independence in negotiations with the upper stratum. It criticized the “Left” and Right opportunist tendencies found in united front work. Speaking on the questions of nations and colonies at the congress, Li Dazhao gave an account of imperialist activities in China and the development of China's national movement.
