The Russian Orthodox Mission in China, also known as the Russian Ecclesiastical Mission, was the effort by Church of Russia to bring Orthodox Christianity to China. The mission originated in the seventeenth century after the forces of Chinese Emperor Kangxi (Kang Hsi) brought Russian captives, including an Orthodox priest, to Beijing, China after the capture of the Russian fortress Albasin. The Mission continued until the Church of China formed in 1956 after the Communist Chinese government required the departure of non-Chinese church officials.
