Yes, but both have matured a great deal, and are continuing to do so at an even more rapid rate now.
The Chinese have solved how to build manufacturing towns in Africa and make them safe for the workers, and not piss anybody off doing it. Quite a feat.
Indeed, yes. I’d quite hope to see a deal where Chinese interests buy, lease, or otherwise peacefully mine Siberia - it would be cheaper, in the long run, then war. Russia has a history (Alaska) of selling resources they couldn’t develop, having under utilized them for centuries, I’d hope to see them follow that template. I’d be even happier if a U.S. leader could parlay their competition to our gain :)
