You should always read scientific publications with a healthy dose of scepticism - not because science isn’t to be trusted, but because trying to falsify it’s results and finding potential issues is an important part of the process.

If you do that, I don’t see why you should treat Chinese papers differently. Sure, a country with an authoritarian government with a cultural emphasis on face might produce some papers that aren’t factual due to that specifically, but dismissing the scientific output of a nation of over a billion people over that seems backwards.
