Back atcha - What’s your game?
Here’s the thing - the UNHCR is an international body, and their definition of human rights are accepted by a large part of the world.
No one country, no matter how populous, gets to redefine human rights and not get criticized for it. Especially when that country has a history of abusing the rights the rest of the world accepts.
But if China can just put forward its own definition and do whatever they want without censure, what stops other countries from doing the same?
ETA: What I’m implying is that states with a record of human rights abuses shouldn’t get to make their own rules.
