The Chinese regime is extremely authoritarian, spies on it's own citizens, implemented a social credit system, arrests people without warrants, makes people disappear for going against the government, and there's a possible active genocide happening against the Uyghurs right now just to name a few.

The West typically wouldn't want to do business with a country like that but tolerates China and doesn't denounce them as much as they normally would because they are too afraid to lose the economic benefits.
