Sounds like they could use some government regulation.
A free press that could hold a democratic government to account would help too. The oligarchic system that rules China is not exactly stellar on the environment.
History shows that no communist nation is. They're still cleaning up the messes Russia had made across Europe and Asia during their 70 year reign of terror.
Well yes. However Western European countries end to be better than the US in this regard and they all have socialist governments at least some of the time. As I said democracy and a free press to keep the government to account is needed. But also good government regulation to stop corporations shitting everything up. The Chinese have none of these and have a strange hybrid capitalist oligarchy that long ceased to bear any resemblance to Marxism despite calling itself that. Not sure there are any communist countries as the USSR was.
