陳炯明
United States of China () is a political concept first devised in the early 1920s by Chen Jiongming of a federalized China modeled closely after the United States of America. Given the political, social and linguistic realities of China in the warlord period, Chen Jiongming believed that a federalist approach was the only feasible way to eventually establish a united, democratic republic. Beginning with Guangdong as a model state, he wanted to organize a "United States of China in the manner of the American experience" through negotiation with federalists from all parts of the country.
