seem to be thoughtless, over-consuming assholes no matter what country you visit.

true, but I have hope at least that the small subset of people who climb mountains (here in China even) can be different.
Kudos to you for packing out the trash left by apparent scumbags. And congrats on a nice climb!
Environmental consciousness does not happen by itself, at least not for most people. What is needed is education in a friendly and respectful manner. I remember when there was trash on popular trails in the Sierras. Nowadays, you are hard pressed to find much. I think people are picking up after themselves and other people, with pride I might add.
I'm not much of an activist normally, but I feel the community of mountaineers in China is small enough that this is possible to change -- they are rich enough to go climbing, and it may be possible to shame some people into changing their behavior.
