I'm not sure on the tibet part specifically, but I've definitely heard people express environmental concerns relating to China or African nations going through industrial growth or milestones that the US and European nations went through already.
Which isn't wrong, since those milestones are what caused the ecological problems we have in the first place. It's just not going to sit well if someone says not to do what they did, and instead just buy the next iteration and be dependent.
The line between "destroying culturally significant traditions" and "but it's my house and I want better plumbing" is fuzzy.







Oh, totally. And it would be fantastic if they found a way to get modernized infrastructure without making our mess worse. But a lot of that solar growth is beholden to external investors, either private equity or governments like China.
Everyone wants to do some resource exploitation in Africa, and China is no exception. Just because they have a stance of indignation over "don't do X, buy Y from me instead" doesn't mean they won't do the exact same thing with their Y.
