The Chinese Orthodox Church is an autonomous Eastern Orthodox Christian church in China. An organized Orthodox presence was maintained in the region as early as the 17th century as a child of the Russian Orthodox Church, which granted the Chinese Church autonomy in 1957 amidst its ongoing suppression in the Soviet Union.

The Russian Orthodox Church, alternatively legally known as the Moscow Patriarchate, is an autocephalous Eastern Orthodox Christian church. It has 194 dioceses inside Russia. The primate of the ROC is the Patriarch of Moscow and all Rus'.
