Well, the muslims are a group the Chinese are “most concerned” about (as said); Christianity and Falun Gong do not currently present the same potential of violence.
Yes, they’re opposed to anything organized outside of state control, though welcome business / trade with Islamic and Christian nations so long as it’s advantageous for the Chinese gov’t.
I may disagree with China’s form of government, but at least they look out for their own interests. Wish we’d try that sometime in this country.
