WEST PALM BEACH, Fla. — Just two days after President-elect Donald Trump threatened to implement significant new tariffs on Canada and Mexico as part of his strategy to combat illegal immigration and drug trafficking, he announced that he had a discussion with the Mexican president, who reportedly agreed to take measures to halt migration through Mexico.

In a post on his Truth Social account late Wednesday, Trump touted the conversation as a means of “effectively closing our Southern Border,” referring to it as a “very productive conversation.”

Mexican President Claudia Sheinbaum confirmed the dialogue with Trump, describing it as an “excellent conversation.” She highlighted their discussion on Mexico’s approach to migration and noted that the caravans are not making it to the northern U.S. border because Mexico is actively managing the situation.

“We also spoke about enhancing cooperation on security matters while respecting our sovereignty and the ongoing efforts we are making to curb fentanyl consumption,” Sheinbaum shared on her social media platform.

The implications of the dialogue for Trump’s proposed tariffs remain uncertain.

Earlier in the week, Trump announced intentions to impose a 25% tariff on all goods entering the U.S. from Canada and Mexico as one of his first executive actions scheduled for January 20. In his declaration, he criticized the rising number of migrants illegally crossing into the United States, despite reports indicating that border apprehensions are currently near four-year lows.

The decline in illegal migration across the southern border can be attributed in part to the Biden administration’s efforts to enhance collaboration with Mexico—an aspect that Trump appears to be acknowledging in his remarks.

Data indicates that arrivals at the U.S.-Mexico border have decreased by 40% from a record high in December, with U.S. officials largely attributing this drop to increased monitoring and enforcement around rail yards and highway checkpoints in Mexico.
