I stand by my position. In addition, their "one child per family" policy will play into this.

China is not going to war (combat war) with anyone. Will they hack the crap out of a country's computer networks and clone their military technology ? yes. will they put soldiers on the ground and engage combat or drop missiles ?

No.

Will China "take credit" for de-escalating tensions with NK? Sure. And that's fine. Like I said, the result is the same.
