The US, Canada, and Mexico officially signed a new trilateral trade deal on Friday at the G20 summit in Buenos Aires. It’s known as the USMCA, or the United States-Mexico-Canada Agreement. (At least in the United States.)
Trump, Mexican President Enrique Peña Nieto, and Canadian Prime Minister Justin Trudeau celebrated the new deal on Friday, November 30, 2018 and Trump referred to it as a “groundbreaking agreement” during his brief remarks.
