“There’s no way that could happen,” Videgaray said on Mexican television a few days after his appointment.

“There are no circumstances… not even the best possible trade deal, investments, support which would justify taking a step that would violate the dignity of Mexicans to such an extent.”

The wall has been a bone of contention between Trump and Mexico since the businessman launched his presidential campaign in June 2015, accusing Mexico of sending rapists and drug dealers across the border into the United States.

Trump said on Friday that Mexico would repay the United States for the wall, a day after news emerged that the New Yorker’s transition team was exploring getting the Republican-led Congress to vote to approve the funding.

Previously Mexico‘s finance minister, Videgaray played a key role in setting up Trump’s hastily arranged visit to Mexico City at the end of August, which turned into a public relations disaster for President Enrique Pena Nieto.

Videgaray stepped down as finance minister a week later. Officials say he has played an important role in informal talks with Trump’s transition team, particularly his son-in-law Jared Kushner who is set to become a senior White House adviser.

During the television interview, Videgaray said he had a “very favorable impression” of Kushner, whom he described as “extraordinarily competent.” Contact with Kushner had come about through connections on Wall Street, Videgaray said.

Videgaray said setting up a meeting between Pena Nieto and Trump once the American takes office on Jan. 20 was a priority.

Trump has vowed to ditch a joint trade deal with Mexico if he cannot renegotiate it in the United States’ favor, and has threatened to slap a hefty border tax on goods produced in Mexico, notably from its burgeoning automobile sector.

Last week Ford abruptly canceled a planned $1.6 billion investment in Mexico, and Trump promptly thanked the firm.

“I think the uncertainty (over trade) is doing a lot of harm to investment decisions in the automotive sector and many other sectors,” Videgaray said.

The foreign minister said Mexico would also need to undertake more trade missions than ever before in 2017 in Asia, Europe and Latin America to diversify its base.
