President Donald Trump agreed to delay the imposition of sweeping tariffs on Mexico by one month after Mexican President Claudia Sheinbaum promised to send 10,000 troops to the Southern border to help the U.S. curb illegal immigration and fentanyl trafficking.

The agreement came Monday morning, two days after Trump signed an executive order authorizing 25 percent tariffs on imported goods from Mexico and Canada and a 10 percent tariff on products from China. Trump spoke with Sheinbaum and Canadian Prime Minister Justin Trudeau, both of whom vowed a retaliatory response to the U.S. tariffs.

Trump confirmed the long-awaited tariffs on Mexico were paused for one month to allow room for negotiations, hours before the measures were set to take effect.

“We further agreed to immediately pause the anticipated tariffs for a one month period during which we will have negotiations headed by Secretary of State Marco Rubio, Secretary of Treasury Scott Bessent, and Secretary of Commerce Howard Lutnick, and high-level Representatives of Mexico,” Trump posted on Truth Social. “I look forward to participating in those negotiations, with President Sheinbaum, as we attempt to achieve a ‘deal’ between our two Countries.”

No reported agreement has been made with Canada as of Monday morning. Trudeau announced Saturday night that Canada would begin imposing 25 percent tariffs on U.S. goods in response to Trump’s tariffs.

Trump authorized the tariffs in order to ensure cooperation from Mexico, Canada, and China in helping combat the record inflow of illegal immigrants and fentanyl supplies into the U.S.
