Fair I was filling in the blanks of your argument. I disagree with China having to own the accusations made against its treatment of its Uighur minority, there’s a lot of evidence out there that this is a US funded campaign to discredit China internationally, similar to how they used Tibet as a propaganda campaign in the 90’s.
Regardless, I agree China has done bad things, similar to many powers in the world, and they should own (be accountable to) those mistakes. In this context I don’t see the need for them to own anything however, instead they should continue to defend their reputation, and point out human rights issues in the west.
