If the US decides to start applying fees on aluminum and steel exports from Mexico as a way to exert pressure in the renegotiation of the North American Free Trade Agreement (NAFTA) from June 1st onward, Mexico will meet such measures with equivalent fees. This is how Kenneth Smith, leader of the Technical Negotiation of the trilateral trade agreement, responded to the warning made this Monday by the Secretary of Commerce of the United States, Wilbur Ross. "Depending on where we are in NAFTA on June 1, the US president (Donald Trump) will decide whether or not to extend his situation. It can not be predicted at the moment, "Ross said Monday. Smith made it clear that the Mexican team will not give in to any pressure from issues related to politics or to the Section 232 of the United States regulation, which endorses limiting imports with the argument of national security.
