I don't think whether a country is an importer or an exporter matters at this point. This is likely going to develop into a matter of national security. Nations cannot allow most of their domestic industries to be destroyed.
If the US doesn't reverse course soon, I think we'll start seeing large-scale closure of international markets to US companies very soon. Even with US retaliation, there is no other option.
Zero chance of that happening. Europe has already largely deindustrialized and it never closed itself to China. Europe also tried to stop buying Russian oil and failed due to transshipment through India.
It's really sad seeing how little so many of us Europeans understand the situation. America and China hold all the cards, Europe holds none. It makes very little that is both unique and strategic. Decades of left wing economic policies are coming home to roost and there's no way to turn the ship around now.
