Trump also warned USA lawmakers, who have become increasingly uneasy that the new trade deal, formally signalled in a letter to Congress Friday, might not include Canada. "If we don't make a fair deal for the USA after decades of abuse, Canada will be out".
The consultations took place after Canadian and American negotiators failed to reach a deal by Friday's deadline amid reports that Trump had said he would not compromise at all to get a deal with Canada. Negotiations are to resume next Wednesday.
He says on Twitter that a deal will go ahead with or without Canada's involvement, and if Congress tries to intervene, he will "terminate NAFTA entirely".
Foreign Affairs Minister Chrystia Freeland has said she remains optimistic that a deal can be reached.
Lawmakers on Friday warned that a deal with Mexico could struggle to win approval from Congress unless Canada was also included.
Trump has railed against the publication of his comments in tweets and public statements, though he did not appear to dispute the substance of his remarks.
"Remember, NAFTA was one of the WORST Trade Deals ever made". "And we will only agree to a deal that is a good deal for Canada".
U.S. President Donald Trump delivers remarks before signing an executive order on strengthening retirement security in America at Harris Conference Center in Charlotte, NC, U.S., August 31, 2018. Even the Vat Tax was not accounted for. Canada is the second-biggest trading partner of the USA, and Mexico is the third.
Trump also threatened Saturday that if Congress attempted to interfere with these negotiations, he would simply "terminate & we will be far better off".
