China probably didn't force them directly. That's the thing about authoritarianism. You learn what you think the government wants, and you enforce it on yourself, potentially going above and beyond what they'd ever even think of demanding upon you. You stop being willing to say things that are critical of the central government out loud, and eventually you even stop THINKING things that are critical of the central government through practice.
