Ruan Zhenduo served in many cabinet-level positions in what puppet state in Northeast China and Inner Mongolia, which was governed under a form of constitutional monarchy?
Manchukuo Manchukuo (: "Mǎnzhōuguó"literally: " State of Manchuria" ) was a puppet state in Northeast China and Inner Mongolia, which was governed under a form of constitutional monarchy. The area, collectively known as Manchuria by westerners and Japanese, was designated by China's erstwhile Qing Dynasty as the "homeland" of the ruling family's ethnic group, the Manchus. In 1931, the region was seized by Japan following the Mukden Incident and a pro-Japanese government was installed one year later with Puyi, the last Qing emperor, as the nominal regent and emperor. Manchukuo's government was abolished in 1945 after the defeat of Imperial Japan at the end of World War II. The territories formally claimed by the puppet state were first seized in the Soviet invasion of Manchuria in August 1945, and then formally transferred to Chinese administration in the following year.
Northeastern Jiangxi Soviet The Northeastern Jiangxi Soviet () was a constituent part of the Chinese Soviet Republic (1931 - November 1935). Any military threat it posed to the Nationalist Party-controlled Chinese State (1927–1949) had been roundly neutered by an early 1931 campaign (while it was still known as the North-eastern Jiangxi Revolutionary Base Area), and thus the area was never going to make a formidable component soviet of the CSR.
