I say scrap all tariffs with all the democratic nations, the friendly ones, and just slap it on all the dictatorships. 300% tax.
But do this only if those countries also tariff China heavily. Use tax as a means to destabilise dictatorships, so that their economies shut down.
Tell all their citizens that if they overthrow their government and install democracy, the tariffs will be lifted.
Use tax to unseat dictators. That's how dictatorships fall; people have nothing left to lose so they coup.
