To answer, if you look at Chinese government's behaviour, they're only interested in controlling their country, not anyone elses (cue shouts of "Free Tibet"). And it's also my belief that it's done to stop external players influences hijacking their political process. When it comes to personal freedom, at least you know where you stand in China or Russia. In America, they pretend it's still like the spirit of the Founding Fathers and the Bill of Rights. The Founding Fathers are doing a dance like that possession scene in The Exorcist, however (spinning in mid air, for the those that need it explaining)
