The pollution is the direct result of other countries outsourcing their manufacturing to exploit chinese labor for increased profits, and they’re rapidly reducing that pollution with the infrastructure investments I mentioned. The censorship is clearly necessary, as evidenced by the US getting absolutely bodied by relatively simple online disinfo campaigns. And the ethnic cleansing is fictional, fucking duh. Uighurs are directly represented in the ruling party, their language is present in official documents and on their currency. Xinjiang is literally open to foreign tourism right now, you could go there yourself and learn better in person.
