How To Avoid Subjugation To China

The EU is vexed that it imports so much from China, yet exports more to Switzerland (whose existence it barely acknowledges - look at the map on Euro notes) than to the People's Republic. Well, I have an idea. Why not import nothing from China, or anywhere else, that could not be made, not even in the EU, but in the specific country in question? Why not have laws to that effect, and enforce them vigorously? It's just a thought.
