Mexican President Claudia Sheinbaum and President elect Donald Trump
CNN  — 

Mexican President Claudia Sheinbaum denied proposing to US President-elect Donald Trump that Mexico will close its border with the United States as he claimed in a post on Truth Social.

“Everyone has their own way of communicating, but I can assure you, I give you the certainty that we would never — and we would be incapable of it — propose that we would close the border,” Sheinbaum said during her regular morning news conference Thursday. “It has never been our approach and of course we don’t agree with that.”

Sheinbaum’s remarks came after Trump said Wednesday that the pair had a “productive conversation” during their first talks since Trump announced tariffs against Mexico earlier this week that would slap a 25% tariff on all products from that country and from Canada. He claimed the move would be in retaliation for illegal immigration and “crime and drugs” coming across the border.

“Just had a wonderful conversation with the new President of Mexico, Claudia Sheinbaum Pardo. She has agreed to stop Migration through Mexico, and into the United States, effectively closing our Southern Border. We also talked about what can be done to stop the massive drug inflow into the United States, and also, U.S. consumption of these drugs. It was a very productive conversation!” Trump posted on Truth Social.

In her own statement about the conversation, Sheinbaum said she shared Mexico’s immigration strategy with the president-elect and stressed that her country’s “position is not to close borders.”

“In our conversation with President Trump, I explained to him the comprehensive strategy that Mexico has followed to address the migration phenomenon, respecting human rights,” Sheinbaum said Wednesday on X. Thanks to this, migrants and caravans are assisted before they arrive at the border. We reiterate that Mexico’s position is not to close borders but to build bridges between governments and between peoples.”

Sheinbaum had previously said that Mexico has worked with the Biden administration to address the flow of migrants through the country, leading to a 75% reduction in US border crossings over the past year. And after the call with Trump on Wednesday, she did not outline any new policies she planned to put in place in order to avoid tariffs, focusing instead on how her country had already acted to address the crisis.

It is not yet clear what will come of the disconnect between Trump’s quick victory lap and Sheinbaum’s promotion of the status quo. But the episode was reminiscent of Trump’s first term as president, when his bombastic rhetoric surrounding his dealings with Mexico did not always match the situation on the ground.

Trump, for example, pledged to build a wall along the southern border and have Mexico pay for it. Under Trump, the US ultimately constructed 458 miles of border barriers, including 373 miles of wall replacing dilapidated or outdated structures. The total fell short of the 1,000 miles Trump repeatedly asserted was needed, and Mexico did not pay for it.

The early interactions between Trump and Sheinbaum will be closely monitored as he prepares to implement his long-promised plan to end undocumented migration into the US and deport those who have entered the country illegally.

Trump’s team is already considering executive action to bring back a program informally known as “remain in Mexico,” which requires migrants to stay in Mexico during their immigration proceedings in the US.

Sheinbaum previously said she had a “cordial” call with Trump shortly after his electoral victory where they discussed the “good relationship” between Mexico and the US, according to a post on X.

Wednesday’s call between Trump and Sheinbaum came two days after the president-elect promised promised massive hikes in tariffs on goods coming from Mexico, Canada and China starting on the first day of his administration.

“On January 20th, as one of my many first Executive Orders, I will sign all necessary documents to charge Mexico and Canada a 25% Tariff on ALL products coming into the United States, and its ridiculous Open Borders,” Trump posted on his Truth Social platform. “This Tariff will remain in effect until such time as Drugs, in particular Fentanyl, and all Illegal Aliens stop this Invasion of our Country!”

Sheinbaum responded to the social media post with a fiery letter of her own in which she suggested Mexico would retaliate with counter-tariffs if Trump went through with his threat.

In his comments Wednesday, Trump did not say whether he would stand by the pledge or anything Sheinbaum had said addressed his concerns. Trump’s transition team did not immediately respond when asked by CNN if he still intended to hit the US southern neighbor with a 25% tariff when he takes office. Nor did Sheinbaum suggest she had received assurances from Trump that he was backing down from the threat.

President Joe Biden, who had stressed on the campaign trail that Trump’s foreign policy could pose a danger to the US’ relationship with allies and key trading partners, said Thursday that he hopes the president-elect “rethinks” his tariff plan, calling it “counterproductive.”

“We have an unusual situation in America. We’re surrounded by the Pacific Ocean, the Atlantic Ocean, and two allies: Mexico and Canada. The last thing we need to do is begin to screw up both relationships,” Biden said.

Canadian Prime Minister Justin Trudeau called Trump shortly after his social media post on Monday, an official with the prime minister’s office said. The brief call was focused on border security and trade, a senior Canadian government source told CNN. They characterized the call as productive and said that Trudeau and Trump promised to stay in touch in the days to come.

Responding to Trump’s announcement, Chinese Embassy spokesperson Liu Pengyu said his country has been in communication with the US about counternarcotics operations and that “the idea of China knowingly allowing fentanyl precursors to flow into the United States runs completely counter to facts and reality.”

“About the issue of US tariffs on China, China believes that China-US economic and trade cooperation is mutually beneficial in nature. No one will win a trade war or a tariff war,” Liu said in a statement to CNN.
