And why on earth should someone in - The Americas, Europe, Africa, Oceania, rest-of-Asia care if China wastes their OWN water? China can do whatever they want with their own natural resources. As long as they aren't actively harming other nations, it's their prerogative.

So yes.. of COURSE people in the US are going to care when a Chinese company comes to the US and starts wasting our natural, shared resources while at the same time not caring at all when China wastes their own shared natural resources. I'm not sure why that would seem odd or confuse you in the least.

In other news: Lots of people are pissed that the current US president is removing protections on national monuments. Same people don't bat an eye when Xi Jinping refuses to create national monuments in China. The sky is blue. Water is wet.
