On 20 November, a conference in the Chinese government was convened, but the Guangzhou faction of the Kuomintang insisted that Chiang Kai-shek step down to take responsibility for the Manchurian debacle. On 15 December, Chiang resigned as the Chairman of the Nationalist Government and was replaced as Premier of the Republic of China (head of the Executive Yuan) by Sun Fo, son of Sun Yat-sen. Jinzhou, another city in Liaoning, was lost to the Japanese in early January 1932. As a result, Wang Jingwei replaced Sun Fo as the Premier.
