I know that China is an authoritarian near-dictatorial country that oppresses minorities and commits cultural genocide. And I am not an American.

That does not seem to be all that related to the original post I was answering to. An average person / citizen / visitor has way less to worry about around (trained) Chinese police than they have to worry about around an (gangster) American ICE agent.

You should also know that China doesn't have as much rule of law as America and indeed average people have a lot to worry about around the police, and generally are very careful not to do things that will get them beaten up. But it happens nontheless - violent assaults on street sellers by police, for instance. In China, people are actually scared of the police because the policemen have so much arbitrary power. They're not strictly and fairly enforcing the law at all.
