Um, you mean cuts off 25% of our potential supply. What happens then is we exercise more of our options (or just negotiate new deals) elsewhere to make up for it. In short, pretty much the same thing that happened when China declared war in the first place. However many plants in however many countries they bomb, we're still better off than if we had used and they had bombed the same plants in the US. Fewer American casualties, certainly. (Are you expecting China to declare war on us and bomb every country in the world that we do business with? That seems like a pretty expensive and unlikely proposition. It's also worth noting that international trade all by itself tends to improve communications and reduce the potential for hostilities.)
