The Wang Jingwei regime is the common term to describe the Reorganized National Government of the Republic of China which existed a puppet state of the Empire of Japan in eastern China in co-terminus with the Nationalist government of the Republic of China under Chiang Kai-shek, which was fighting Japan along with the other Allies of World War II. The country functioned as a dictatorship under Wang Jingwei, formerly a high-ranking official of the Nationalist Kuomintang (KMT). The region it administered was initially seized by Japan during the late 1930s at the beginning of the Second Sino-Japanese War.

A puppet state, puppet régime, puppet government or dummy government is a state that is de jure independent but de facto completely dependent upon an outside power and subject to its orders. Puppet states have nominal sovereignty, except that a foreign power effectively exercises control through economic or military support. By leaving a local government in existence the outside power evades all responsibility, while at the same time successfully paralysing the local government they tolerate.
