Modern China has nothing in common with ancient China except for the territory (and even that is quite vague). It is a completely different people, a completely different country. Even now, there is a clear distinction between Northern and Southern China, and four hundred years ago, these were two different states with different ethnic compositions. Only the name remains from the old China (and even then, the inhabitants themselves call themselves the people of the Celestial Empire or Han, in honor of one of the ancient dynasties). So, the name Russia may remain, but in reality, it will be a province of China. As for the Mongols, they were experiencing a surge of passion, an outburst of youthful energy at that time. That's why they burned out and aged prematurely. Besides, it's not such a poor country. Almost every yurt has its own solar panel. I know, I talked to a professor from Mongolia.
