Countries don't decide shit for where products are made. Does Japan tell Nintendo or Sony (or US gov't to Microsoft) they can't make their game systems in China? No, they don't, and they won't be able to.
All that will happen after this is countries will ensure in an emergency situation they have contingency plans to rapidly speed up manufacture of a few select items ... hospital gowns/masks, ventilators, and testing equipment.
But that's a tiny fraction of things to manufacture in the grand scheme of things, how many ventilators can you manufacture a year from now when this has passed, it will be pointless and nationalized factories for that sort of thing will just be shut down. Everything else will just continue on being made where it was.
