You're just meme-ing, right? Or how did you come to that conclusion? Because neither BGP nor physics works like that. The ping would be significantly worse, even in the hypothetical case of RU-CN laying a huge direct fiber cable from Moscow to Chengdu. The only exception would be those in the Far East (which is most likely already choosing routes through China), as the overwhelming majority of Russia lives in the western side.

But it's not even a cutoff, there's still many different routes through Europe that will be chosen. That's the beauty of the Internet, it will always get routed to its destination unless someone specifically blocks it :) And that's also why so much traffic goes over those lines, as it's the cheapest path; internet routing is behaving exactly as intended.
