Hello, all replies at this point I think are ~cultural. Caspianreport (others to probs but that’s where I heard it) iirc says a lot of China water comes from Tibet region. Many big Chinese rivers start there. This is first comment ever, god knows how long I’ve lurked, please take it easy on me. Confirmation bias link and quote: https://depts.washington.edu/chinaciv/geo/proper.htm “ Two great rivers run through China Proper: the Yellow River in the north, and the Yangtze (or Yangzi ) River to the south. In fact, most of China Proper belongs to the drainage-basins of these two rivers. Both originate to the far west in the Tibetan Plateau.”
