I will let better minds than mine to answer. However logic tells me a substantial increase in tariffs will have an effect and our dear Asian friends and their "saving face" culture does not allow them to sit idly by.
Trump has said repeatedly and I agree with him that regarding China he will never have to do it. Just saying he’s going to put a tariff on China will scare them into quitting the currency manipulation. They are already crying like a stuck pig about it and he’s not even in office. So is Mexico. LOL!
