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.
Well that is called as maintaining the international relations and at the same time maintaining your countries economy in proper way. The corporate relations are very much different, the cost cutting and labour cost is touching the skies and I guess such importing makes things very much easier for most of the manufacturers. US is giant continent and its needs are expanding like space so its always better to have extra sourced facilities to work for them. Its cheap and that cheap process is what making products and services cheap inside the country as well. So its benefit for the people and nation as well.
