In early 1927, shortly before Chiang captured Shanghai and moved the capital to Nanjing, Wang's faction declared the capital of the Republic to be Wuhan. While attempting to direct the government from Wuhan, Wang was notable for his close collaboration with leading communist figures, including Mao Zedong, Chen Duxiu, and Borodin, and for his faction's provocative land reform policies. Wang later blamed the failure of his Wuhan government on its excessive adoption of communist agendas. Wang's regime was opposed by Chiang Kai-shek, who was in the midst of a bloody purge of communists in Shanghai and was calling for a push farther north. The separation between the governments of Wang and Chiang are known as the "Ninghan Separation" ().
