The US accounts for just under the 19% of Chinese exports. That is not trivial, but the domestic (and non-US international) market is growing fast enough that it can absorb that hit faster than it would take other countries to develop capacity to make those goods at the standard that American buyers demand. Sure, it would mean lost economical potential for China, but by no means would it leave China with no place to send its manufactured goods.
