On Wednesday, August 16, Canada, Mexico, and the U.S. began the opening round of renegotiations to NAFTA in Washington, D.C. The opening round lasted through Sunday and was largely closed-door; however, the U.S. put forth its objectives for the negotiations last month. The three top negotiators, U.S. Trade Representative Robert Lighthizer, Canadian Foreign Minister Chrystia Freeland, and Mexican Economy Secretary Ildefonso Guajardo, began the day with opening statements.
