The re-education program in Xinjiang seems to have ended already and fulfilled its stated purpose. Tibet had slavery and was semi-feudalist, while the Dalai Lama owned slaves and was working with the CIA. Life expectancy dramatically improved along with many other metrics like literacy rates once the PLA ended slavery and feudalism. For the DPRK, they maintain trade relations with them, the most sanctioned country on the planet and one of the most heavily bombed. HK was a British Colony to be returned to the PRC, and now most Hong Kong residents would rather be integrated with the Chinese economy.

I think you need to investigate more of these topics if you’re going to list them off as points.
