The Reorganized National Government of the Republic of China, commonly described as the Wang Jingwei regime, was a puppet state of the Empire of Japan in eastern China. It existed coterminous with the Nationalist government of the Republic of China under Chiang Kai-shek, which was fighting Japan alongside the other Allies of World War II. The country functioned as a dictatorship under Wang Jingwei, formerly a high-ranking official of the Kuomintang (KMT) party. The region it administered was initially seized by Japan during the late 1930s at the beginning of the Second Sino-Japanese War.
Wang, a rival of Chiang Kai-shek and member of the pro-peace faction of the KMT, defected to the Japanese side and formed a collaborationist government in occupied Nanjing in 1940, as well as a concurrent collaborationist Kuomintang that ruled the new government. The new state claimed the entirety of China (outside the Japanese puppet state of Manchukuo) during its existence, portraying itself as the legitimate inheritors of the Xinhai Revolution and Sun Yat-sen's legacy as opposed to Chiang's government in Chongqing, but effectively only Japanese-occupied territory was under its direct control. Its international recognition was limited to other members of the Anti-Comintern Pact, of which it was a signatory. The Reorganized National Government existed until the end of World War II and the surrender of Japan in August 1945, at which point the regime was dissolved and many of its leading members were executed for treason.
