Kuomintang (Wang Jingwei)
During the Second Sino-Japanese War, Wang Jingwei, former Premier of the Republic of China and Vice Director-General of the Kuomintang (Chinese Nationalist Party), split from the party in 1939 and established a new Kuomintang in Nanjing. Wang, who collaborated with the Japanese, intended to distance the new party from the Kuomintang led by Chiang Kai-shek in Chongqing.
