> hard to find a supply chain for manufactured products that doesn't have a significant dependency on China. That makes it hard to fight a war with China, trade or otherwise.

You don't ban those products, you put big tariffs on them. That way, anyone who has the option to source stuff elsewhere does so.

And you deliberately act erratically with tariffs - adding and removing them at short notice - so that lots of companies think it is just too risky to trade with China, and move manufacturing elsewhere as insurance.
