Exactly. Xi must be absolutely laughing himself to sleep every day. He has solved all of China's oil, mineral, grain and fresh water supply problems for the next half century. They have unquestioned top dog influence over the Central Asian republics now, a weaker rival for bribable global anti-western allies, and can demand anything from Russia that can't be refused going forward. Including access to the North Pacific, which China has never, ever had.
All without expending a single soldier or loss of a single piece of hardware.
