WASHINGTON — The foreign ministers of Mexico and Canada presented a unified front ahead of potential trade talks with Donald Trump’s administration, stressing the North American Free Trade Agreement has benefited all three countries.

Mexico’s Luis Videgaray and Canada’s Chrystia Freeland said NAFTA should be renegotiated with all three nations seated at the table, rather than in bilateral discussions.

‘‘We very much recognize that NAFTA is a three-country agreement,’’ Freeland said Tuesday at a panel discussion with Videgaray in Toronto. ‘‘We really value our relationship with Mexico.’’

Their talks come after Trump said trade with Canada only needed a ‘‘tweak,’’ as opposed to a more thorough re-set with Mexico, a comment he made after Canadian Prime Minister Justin Trudeau’s visited the White House last week.

Mexican President Enrique Pena Nieto canceled a January meeting with Trump after he tweeted that Nieto shouldn’t come unless Mexico was prepared to pay for a border wall.

Mexico’s relationship with the United States goes deeper than Trump’s ‘‘damaging’’ rhetoric, Videgaray said. He has been to meetings in Washington twice since the president’s inauguration and said he was confident the two nations’ issues could be resolved. ‘‘We will work it out in a way that is constructive and positive for both countries,’’ the foreign minister said.

Earlier Tuesday, Mexican Economy Minister Ildefonso Guajardo said that he expected NAFTA negotiations to start in the summer and that Mexico wouldn’t initiate talk about tariffs, calling any discussion of new import taxes a ‘‘Pandora’s box.’’

‘‘Nothing in the new NAFTA should be a step backward,’’ he said.

Freeland took a more reserved position, saying Trump’s trade team, including commerce secretary nominee Wilbur Ross, have yet to be confirmed. As a result, she said, Canada has had no specific discussions with the United States yet about NAFTA.

‘‘We all collectively have to be quite careful not to get ahead of ourselves,’’ she said.

The morning event began with remarks by Brian Mulroney, a former Canadian prime minister who has been acting as informal emissary to Trump for Trudeau. Mulroney, who signed NAFTA in 1992, and who spoke to the president this weekend at Mar-a-Lago in Florida, was asked about reports that Canada would abandon its southern partner and deal directly with the United States.

‘‘You can forget this under-the-bus argument,’’ Mulroney said. ‘‘This under-the-bus stuff is for losers, not winners, and Canada is a winner.’’
