When you say individual freedom, I think you really mean individual political freedom. Excluding Xinjian, China has probably more freedom in day-to-day life for individuals than, say, America because it has less violent crime, less imprisonment, and lower regulatory barriers to doing business. It might be that it can only achieve these good things by restricting political freedom.
Even when they do restrict individual freedom, like with the one child policy, and internal travel restrictions, that has the aim of making the overall society better. There's a trade-off between individual freedom and survival and growth of the society. Too much freedom is anarchy and too little is totalitarianism. Where is the sweet spot?
