".... but focused on SK and US troops in SK."

I doubt it. Neither China or Russia are sure the numbskull in NK won't launch a nuke at them since he doesn't come to heel even after they help him.

As long as China has a say in who runs NK instead of being reunited with SK without any Chinese say in how it is organized and run they'd probably be glad to see the leadership change. They have plenty of problems with NK other than nukes, too.

No evidence of that. NK leaders have never said a word about attacking China or Russia. NK's wrath has always been directed at SK and US.
