Trump, along with Canadian Prime Minister Justin Trudeau and outgoing Mexican President Enrique Peña Nieto signed a new pact succeeding more than a year's debate.
The move comes as leaders in congress mull over the agreement, with neither Republicans nor Democrats happy with the new agreement.
Canada's pressure to include "soft things" like labour standards in the new North American free-trade treaty will help secure critical support for the deal from Democrats in the United States Congress, the Canadian ambassador to the USA says.
Hailing the deal as "modern and balanced", the president said at the signing ceremony that it has been "well-reviewed" and he doesn't expect to have much problem in Congress. The deal eliminates Canada's unfair Class 6 and Class 7 milk pricing schemes, opens additional access to United States dairy into Canada, and imposes new disciplines on Canada's supply management system. "The president needs to talk to Congress on this", the Ohio Democrat told CNN on Sunday. Grassley vowed to usher the deal through Congress, saying it'll benefit the USA economy and bolster agriculture interests in the Midwest. "We look forward to working with Congress to get USMCA passed into law as quickly as possible".
The U.S. Chamber of Commerce said previous year that exiting NAFTA without a new deal could devastate American agriculture, cost hundreds of thousands of jobs and "be an economic, political and national-security disaster".
Senator Elizabeth Warren, a Democrat from MA, speaks at American University in Washington, D.C., U.S., on Thursday, Nov. 29, 2018. But, of course, the relationship between Democrats and Donald Trump is pretty frayed and Nancy Pelosi, who is likely to be the next speaker of the House of Representatives may decide to take a page from Senate Majority Leader Mitch McConnell's book who, when Barack Obama, was President of the United States, basically refused to pass anything that had Barack Obama's support behind it.
"I think they're betting on Congress not letting it all go to hell", she said.
"While there's a lot to like in this new agreement, I'm disappointed that the Section 232 tariffs on Canada and Mexico still remain in place", Republican Senator Rob Portman said in a statement on Friday.
Trump hailed it as "one of the most important, and largest, Trade Deals in US and World History" on Twitter shortly after the signing ceremony.
The MP also pointed out that the ongoing tariff tiff with the Trump administration has not been dealt with, an issue that affects the auto industry and manufacturing in the Windsor-Essex area.
"The United States, Mexico and Canada worked so well together in crafting this great document". "I think that's how he thinks he's going to whip votes".
"As now drafted this deal will put Florida seasonal vegetable growers out of business", Rubio wrote.
