Oh, what u r saying here is patronizing. Before you start to criticize others or another country, shouldn't you do some basic justification or research. Free speech is not about just blindly saying whatever u want. That's irresponsible. Ppl should be responsible for whatever they say as grown man.
When you are blaming China's behavior or any other country's behavior, do u see any proof abt those so-called bad behaviors? Or u just read some news and followed whatever ppl are saying.
In addition, every country has its own problems and own culture. Try to respect others first. If there is improvement other should have, what is needed is constructive suggestion instead of patronizing blame.
Indeed I am disappointed abt this student's behavior as he has studied in China for sometime and he made friends in China as well, he should have a good understanding abt the life there and would understand what had happened there during COVID. He could have been more responsible for what he tweeted.
Did you see any proof showing there is concentration camp in Xinjiang? Or you just read it from news and have you doubted whether the news is fake or not?
