US president-elect Donald Trump declared a win on stopping illegal immigration through Mexico on Wednesday after talking with Mexican president Claudia Sheinbaum. But Sheinbaum suggested Mexico was already doing its part and would not close its borders.

The two spoke just days after Trump threatened to impose sweeping new tariffs on Canada and Mexico as part of his effort to crack down on illegal immigration and drugs.

Trump said Sheinbaum “agreed to stop migration through Mexico.” Sheinbaum indicated separately on social media that she told Trump that Mexico is already “taking care of” migrant caravans, calling it an “excellent conversation.”

“We reiterate that Mexico’s position is not to close borders but to build bridges between governments and between peoples,” Sheinbaum added.

While the state of the proposed tariffs remained unclear, Trump said in a post on his Truth Social account that this was “effectively closing our southern border.” He called it a “very productive conversation.”
