Er... why the fact that US is a net importer from China is a bad thing? (Admittedly, I'm not a US citizen, & I'm not really interested in US's trades so I don't know the numbers but...) I thought US was basically using China as a big factory? US's exports will decrease when manufactured in the US since China's cheap labor is allowing US goods to have a not-that-high price. So really the net-import from China is just something that US should embrace to get the net-exports to other countries.
