President Claudia Sheinbaum said Thursday that she and President-elect Donald Trump agreed in a phone call that their countries would have a “good relationship,” and she dismissed his threat to impose a 25 percent tariff on Mexico’s exports if it didn’t stop the flow of migrants and fentanyl to the United States.

The President of Mexico stopped migrant caravans heading to the U.S.-Mexico border in response to threats of tariffs from U.S. President-elect Donald Trump.

Migrants often gather in groups in southern Mexico as a means of protection from criminal groups. But they almost never make it anywhere near the U.S.-Mexico border.
