China will be a hard nut to crack in any all-out war simply because they have millions of bodies to throw at us. If it continues to take thousands of rounds to take down one enemy soldier–as it did in Vietnam, we may not have enough ammo to do the job. It would be best if we could train our soldiers to concentrate on head-shots every time, but that’s simply not practical…nor does it recognize the realities in any firefight, where we mostly throw out thousands of rounds, hoping that one or two strike the intended targets. Of course, no other army behaves differently–particularly Islamics where “spray and pray” is their preferred method of attack. They’ve been known to attack with empty weapons because they don’t even realize they’re out of ammo, making them easy targets for anyone who can keep his head.

Blockade at the straits of Malacca; you’d have them on their knees within 2 months.
They aren’t self-sufficient. They know this. This is why they’re trying to bring other countries closer into their orbit with the One Belt, One Road initiative.
Build ports in Pakistan, with clear road networks that lead back to China. Circumventing the straits of Malacca.
