Eastern Christianity in Eastern and Central Eurasia

According to the stela, unearthed in the early 1600s, Christianity came to China in A.D. 635, when a Nestorian monk namedAluobenentered the ancient capital of Chang'an -- now modern-day Xi'an -- in central China.

Christianity has been in China far longer than in the Philippines & South Korea. The big difference is Christianity has not spread out throughout East Asia. 

@komodo at one point Christianity existed in Central Asia and Mongolia, along with the Tarim Basin and Tibet, coexisting with Buddhism and Tengriism or other native faiths.

there are a minority of Filipinos who are Christians of the Eastern Rites. The Antiochian Orthodox church has a presence there as well as what used to be the Ancient Church of the East until they split years later.

The Church of the East or the sometimes referred to as Nestorian Church historically had a presence in China during two periods: first from the 7th through the 10th century, and later during the Mongol Yuan Dynasty in the 13th and 14th centuries. Locally, the religion was known as Jingjiao (Chinese: 景教; pinyin: Jǐngjiào; Wade–Giles: Ching³-chiao⁴; lit. 'Luminous Religion').

Orthodox Christianity like the Russians.
