Ok. Sorry, i understood this as a direct threat by Putin/Russia
China is a country to be reckoned with of course, and if they intend to wage war one day it will be much more relentless than what we can imagine now. At least, if you read some contemporary chinese stuff on this matter.
But as said before i think China is not so amused with North Korea, for them the only advantage is it is a buffer and restricting south korean/western influence and power in this region.
I doubt China will let Kim do anything gross without their explicit consent
