Wang Jingwei or Wang Ching-wei (汪精衛) (died 1944) was a member of the left wing of the Kuomintang and is most noted from breaking with Chiang Kai-Shek and forming a Japanese supported collaborationist government in Nanjing.
He died in 1944, and for his part in World War II, he has been vilified by most post-World-War-II Chinese historians.
