What would happen to both economies if the Us stopped outsourcing and producing so much in China?

If the U.S stopped outsourcing and produced their goods themselves it would create the economy worse as the price of those goods would be higher because of the labour cost where it is very very cheap in China compared to the U.S. The thing that would effect China is if the U.S stopped importing as they are the largest importers of Chinese made goods. This would only happen if the U.S found somewhere else to import cheap goods from. The effects for China would be drastic as that is how their economy thrives from direct investment from companies and exporting their goods.
