FOX NEWS -- Mexico has agreed to deploy 10,000 troops to the U.S.-Mexico border in exchange for a one-month delay on President Donald Trump's threatened tariffs, Mexican President Claudia Sheinbaum said Monday.

Sheinbaum made the announcement on social media Monday morning, roughly 12 hours before the tariffs were set to take effect. Trump and Sheinbaum spoke on Monday and agreed that Mexico will do more to combat drug trafficking into the U.S., and that the U.S. will step up efforts to block the flow of firearms into Mexico.

Sheinbaum also said officials with the U.S. and Mexico were beginning talks on wider trade and security issues.

Trump confirmed the deal in his own post on Truth Social, describing the call with Sheinbaum as a "very friendly conversation."

"I just spoke with President Claudia Sheinbaum of Mexico. It was a very friendly conversation wherein she agreed to immediately supply 10,000 Mexican Soldiers on the Border separating Mexico and the United States. These soldiers will be specifically designated to stop the flow of fentanyl, and illegal migrants into our Country," Trump wrote.

"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. I look forward to participating in those negotiations, with President Sheinbaum, as we attempt to achieve a 'deal' between our two Countries," he added.

The deal comes just days after Trump announced 25% tariffs on both Mexico and Canada, as well as 10% tariffs on China. Trump says he spoke with Canadian Prime Minister Justin Trudeau on Monday, but the pair did not reach an agreement. He says they will speak again later Monday.
