I've been reading "Jesus in Beijing," by David Aikman, former Beijing Bureau Chief for Time Magazine, who believes that China is being slowly and quietly Christianized. He reports that Chinese Christians, very much aware of the threat organized religion presents to the government, have adopted the tactic of working with local government, when possible, to demonstrate how Christianity improves the lives and work ethic of its citizens.
Given the historical record of Islam, it would make sense that the Chicoms view it with a much warier eye than Christianity.
Rather than the traditional self-immolating, confrontational mode, Christian missionaries have adopted softer tactics, such as gaining access to the country as English teachers, who, while not allowed to proseletize publicly, are privately spreading their faith.
Whether the trend will hold is a good question, given China's reactionary xenophobic history, but the book is fascinating.
Almost 20 years ago, a confidential government leaders only doc got leaked outlining the good points of Christians and encouraging leaders to hire them etc. as a counter to corruption etc.
