The 25% tariffs, which Trump first threatened in November to demand Mexico and Canada stem the flow of fentanyl and illegal immigrants into the U.S., were among the first foreign policy obstacles for Sheinbaum, who took office in October as Mexico's first woman president and promised to keep a "cool head" during tariff talks.

Mexico is facing a 25% tariff, while Canada would be charged 25% on its imports to the United States and 10% on its energy products. China is facing a 10% additional tariff due to its role in the making and selling of fentanyl, the Trump White House said.
