Steel is very complicated with the chicoms dumping at $200 a ton and then selling through resellers. Bottom line Trump wants fairness and he will get it come hell or high water. Don't think for a moment though he won't negotiate cause he will. But only when it's to our advantage.
If you are a foreign country and you have to negotiate with Donald Trump or his surrogate,prepare to lose.Prepare not to be able to sit down for a while.
And China is using Canada and Mexico to avoid tariffs. It is why Trump is telling Canada and Mexico that they can avoid these steel and aluminum tariffs if required changes are made to NAFTA.
IMO I find it hard to believe that NAFTA will continue. In the end, we will wind up with bilateral agreements. Mexico and Canada are also signatories to the TPP.
