Government of the Republic of China
The term Free China, in the context of the Second Sino-Japanese War, refers to those areas of China not under the control of the Imperial Japanese Army or any of its puppet governments, such as Manchukuo, the Mengjiang government in Suiyuan and Chahar, or the Provisional Government of the Republic of China in Peiping (now Beijing). The term came into more frequent use after the Battle of Nanjing, when Chiang Kai-shek evacuated the government of the Republic of China to Chungking (now Chongqing).
