Political map of East Asia and the Western Pacific 11 May 1928 (Jinan Incident): Aided by the Guangxi clique (New Guangxi clique), the Chinese Nationalists (Kuomintang) drove the Communists (Communist Party of China) into the mountains in late 1927. With the Communists out of the way, Chiang Kaishek (Chiang Kai-shek) was ready to resume his march on Beijing. However when he attacked the Fengtian clique (Fengtian clique), the Japanese intervened, expelling the Nationalists from the strategic city of Jinan (Jinan Incident).
