China has banned its export
Maybe the rest of us should crack their research labs and grab the blueprints.
I am not one who usually advocates such action, but China regularly steals tech info from us. Sauce for the goose & gander.
If we do not do so then I doubt that China will hesitate to use whatever advantage that it has against us.
It is a shame that as a species we do not cooperate for mutual benefit. Maybe something of Darwin as the cause.
