Freedom of the press doesn't exist in China. In fact, the Chinese government directly controls it by owning the largest newspapers and the largest TV stations. The point of that is that the Chinese government often skews the news to look good. That is especially true of pollution. Chinese Ministry of Environmental Protection issued its annual report showed that water pollution is getting slightly worse while air pollution is getting slightly better. I don't buy either claim. There continues to be a mountain of money to be made by investing in companies that can help China clean up its severe pollution.
