汪精卫政权
Zhang Yanqing (; Hepburn: "Chō Enkei"; 1898–1951), was a politician in the early Republic of China who subsequently collaborated with the Japanese imperialists and became the Foreign Minister of Manchukuo, Japan's puppet state. His father Zhang Zhidong was an important official in the later days of the Qing Empire, while his brother Zhang Renli was an official in the Reorganized National Government of China, another Japan's puppet state, making the two brothers as Japanese collaborators.
