Logistics through Tibet wasn’t really a thing until recently, China had to invest there. But it’s not just Nepal, it’s most of Africa, southeast asia, as well as Australia/NZ. China is literally creating markets for its products that simply didn’t exist at all before.
Sure, though I'm not positive that's a good economic strategy outside of perhaps SE Asia. Market size in places like Africa, along with general instability presenting challenges has not made it a great place to invest, unless of course you have state backing and subsidies from, idk, China?
But let's say China develops these markets and they can afford more cars. That's great. That means after China develops them, Western countries can come in and sell their cars too at China's developmental expense. Seems like a win-win all around.
