Eastern Orthodoxy by country
Based on the numbers of adherents, the Eastern Orthodox Church (also known as Eastern Orthodoxy) is the second largest Christian communion in the world after the Roman Catholic Church. The most common estimates of the number of Eastern Orthodox Christians worldwide is approximately 200–260 million. The numerous Protestant groups in the world, if taken all together, outnumber the Eastern Orthodox, but they differ theologically and do not form a single communion.
Chinese Orthodox Church
Although many of them have adopted Tibetan Buddhism, the Evenks of both the Russian Federation and China are a nominally Orthodox Christian people. They are some of the only Asiatic peoples who nominally practice Orthodox Christianity, which they had voluntarily (as opposed to being coerced to do so) adopted. There are also around 3000 Evenks in neighbouring Heilongjiang.
