No they won't. IP address would remain the same, doesn't matter from which Upstream ISP you would route.
Besides that, APNIC - Home gives IP address to countries of Asia region. So China has to borrow IP address of countries which can be easily bullied. And since it will remain a private IP address within that country and ISP, US would never know.
Actually removing routes will not work as the information will be transferred within other domains in couple of hours, Internet convergence is slow, its made to be slow as there are millions of networks connected. Flapping routes will throw Internet in chaos.
What would US do is poison China's IP address and point it towards bit bucket, means show those IP address as unassigned or not taken therefore data to those destinations can be dropped.
In this case also, US has to ask upstream ISP's (Tier 1) like BT, FT, AT&T, Singtel etc etc to not mask their traffic by its IP.
Its very messy, especially for huge country like china.
Or simply cut the back bones physically?
