That is nonsense. Tariffs in narrow circumstances are completely stupid and counterproductive. Applying tariffs on imports from China or any narrow circumstance will just shift that business to other third world, human rights abusers.
The only way it works for the intended purpose is as part of a greater plan including broader tariffs and domestic incentives as Trump has done and is already working again. Tariffs are not Trump's goal, they are the threat intended to initiate serious negotiation to improve trade balance and it works.
