All countries have their own schemes that's natural, but did the west ever dare to claim Tibet or Hongkong are independent countries like you did for Xinjiang? No one dares to do that cause everyone knows that's in possible. China is becoming the world most powerful country, China might not gain more land, but definitely will not lose any.Whoever wants to try will lose their own land to China.
We are Chinese citizens, not you, almost all Chinese people support the Chinese government, rebellions and civil wars are the theme of your part of the world, not our part.
You hope nothing for Chinese citizens, all Chinese citizens have to follow Chinese laws, it's not gonna change, China is one of the only few countries that always has the guts and spine to stick to what she believes and never caves in under western pressures.
