re: Do you think it is fair that Chinese automakers can use Mexico to ship cars tax free?

Help me understand the issue here...

Nissan, Toyota, and Volkswagen can build cars in Mexico and import them tax free into the US, and that's not a problem. GM and Ford can build factories in Mexico, and we don't like it, but we don't tax them for it.

But if a Chinese company tries to do the same thing, we suddenly want to unwind the USMCA (which Trump himself proposed and signed)?

If their cars suck, then either convince the public they shouldn't buy them, or pass regulatory standards they cannot meet. If they are stealing technology (which the Japanese and Koreans are famous for) then use the FTC to crack down on that.

Do we want free trade with Mexico or not? I'm not advocating one way or the other. But if we want free trade, how can we tell Mexico which companies they can accept investment from?
