President Donald Trump says a new trade pact being signed by the United States, Mexico and Canada is a "model agreement that changes the trade landscape forever."

Trump spent more than a year pushing the leaders of Canada and Mexico into agreeing to a rewrite of North American trade rules. Trump, Canadian Prime Minister Justin Trudeau and Mexico's outgoing President Enrique Pena Nieto are signing the new pact Friday at the Group of 20 summit in Buenos Aires, Argentina.

Trump now faces what could prove a more formidable foe: The U.S. Congress, which must ratify the agreement. He says the parties have "taken a lot of barbs and a little abuse" during the renegotiation.

He turned to Trudeau, saying "It's been a battle," but battles sometimes make "good friends."

Trump calls the signing of the new trade agreement "an historic occasion." And despite disputes between them, says Pena Nieto and Trudeau have become his "great friends."
