I thinking on this matter is don't stop, but slow it down. I don't think we should stop imports from China at all. I do believe that we should cut down a bit and start making our own products. We were a country built on manufacturing. What happened? Did we get lazy and in good times we decided buying cheap would be faster? This is a major reason the economy is where it is today, we stopped making and chose buying.
Of course, every country must itself produce goods that are necessary for citizens. And do not blame China. They can give a more or less normal product for a cheap price.
