This is not smart idea. What you propose is a very hostile action that's akin to declaring war on not just China but any country that has involvement with US currency. China is not your enemy. Yes they became number one, but the US economy and Chinese economy are interdependent on one another. The better solution is to wait. Manufacturing costs in China will eventually rise just like the GDP. If the cost rises high enough manufacturing within the US will become viable again. This is exactly what happened with Taiwan and Japan.
