China is fighting an economic war, they aren’t gonna invade the US.
China is fighting to be top dog in Asia and kick us out. Got to humble Japan and South Korea. They might want to have the USA take some of their excess people—or take Guam or Hawaii at best but—it would do them no good to seize the USA. A small war to seize the islands might do the trick. Tyrants want wars to shore them up. Nothing like a few victories to ensure the people’s loyalty.
