I don't think China wants to go head-to-head against U.S. if it attacks N. Korea. China probably wants to make the best out of it by moving in after the dust settles, and get to dictate what will happen afterwards.

No need for heavy fighting with U.S.. Somebody else is going to hunt a prey for China, which can get a chunk of it.

1) Trump has led the world to believe he will act if necessary.
2) The last thing Trump wants is to occupy N. Korea
3) Neither S. Korea nor China want to deal with starving NORK refugees...but SK is RIGHT THERE. No trouble getting to the border.
4) This road give the Chinese an option to go in OR to get to the border fast to stop the flood of refugees.

My 2 cents.
