The Christian religion is no stranger to China. Both Nestorian and Catholics have created many converts only to be shut out by a xenophobic regime. Then a missionary wave in the late 1800s began the conversion of many elites. Several prime ministers of Japan were Christians. A majority of South Korean and Republic of China Presidents were Christian. Yet Christianity remained a small religion overall in Japan and Taiwan. Now, however, Christianity is becoming a religion of the peasant, the worker, and the middle class like in South Korea.
The new converts are both Catholic and Protestant, both independent of the government and controlled by the government. Protestants do lead with the rate of new conversions though.
No spatial data exists to map out the new converts.
