I have worked with people from different countries in European companies, so in general people are nice and the behaviour is not "oh we like people from country X, but not from country Y"

> And do you have any advice for finding a remote job in these places?

Linkedin. The only thing that could be difficult is the timezone difference. Usually, 2 or 3 hours top is what is acceptable. Also, are you planning to work as a contractor? That would be easier. If you want to work as an employee, either the European company has to have a branch in China or the intermediary company they may use should work on China.
