Between left and right: Cooperation and the split between Yu Qiaqing and the CPC during the era of the Northern Expedition

During the Northern Expedition, the Communist Party of China (CPC) had close contact with certain businessmen; one of these was Yu Qiaqing of Shanghai, who played a role in the background of the Three Armed Uprisings of Shanghai Workers. Because of this contact, Yu Qiaqing was regarded as a leading figure of the leftist bourgeoisie. He was also considered an important collaborator with the provisional municipal government after these uprisings. However, his cooperation with the CPC did not jeopardize his alliance with the Nationalist Party. When Chiang Kai-shek, an old friend of his, arrived in Shanghai, Yu soon turned himself into one of Chiang's financial advisors. Although it is hard to argue that Yu Qiaqing's behavior was representative of most businessmen's party preferences, it does demonstrate that some businessmen had a profiteering attitude in politics and were open to taking advantage of the nexus between politics and business. Influenced by the political context and situation, the CPC was also able to flexibly apply its class analysis theory during that time to justify the policy of cooperating with people like Yu Qiaqing. However, the failure of cooperation with the bourgeoisie by 1927 became an excuse for opposing factions within the party to criticize this policy, and even affected the CPC's subsequent policy line afterwards.
