Mexico will leave NAFTA talks if Trump triggers process to withdraw

Mexico will leave the NAFTA negotiating table if U.S. President Donald Trump decides to trigger a 6-month process to withdraw from the trade pact, three Mexican sources with knowledge of the talks told Reuters. Among the most divisive are plans to establish rules of origin for NAFTA goods that would set minimum levels of U.S. content for autos, a sunset clause that would terminate the trade deal if it is not renegotiated every five years, and ending the so-called Chapter 19 dispute mechanism.
