They have a choice.
Cut off trade to the US.
How long do you think that will last till we break?
It wouldn’t take long. Lots of basic things we don’t make here anymore.
We can survive without another shipment of toaster ovens and plastic junk. China can’t survive with massive unemployment. If it went on for any amount of time US industry could fill the gap. You’re forgetting how quickly US industry can retool when necessity mandates. China needs the US market more that the US needs Chinese products.
It would break them, not us.
