Trump says Mexico will stop flow of migrants after speaking with Mexican president following tariff threats

Trump vowed to impose 25% tariffs on Mexico and Canada if both nations failed to do more to stop the flow of illegal immigrants and drugs into the U.S. Sheinbaum, who recently took office, said on Wednesday that Mexico would retaliate if Trump followed through on his promise. 

"If there are U.S. tariffs, Mexico would also raise tariffs," she said during a press conference. 

On Wednesday, Trump said he spoke with his Sheinbaum about the matter. 

In a post on X, Sheinbaum said she spoke with Trump by phone and that the two discussed "strengthening collaboration on security issues" and that the conversation was "excellent," Reuters reported. 

In a post on X, Sheinbaum said she explained the "comprehensive strategy" Mexico has employed to address the "the migration phenomenon, respecting human rights."

"Thanks to this, migrants and caravans are assisted before they reach the border," she wrote. "We reiterate that Mexico's position is not to close borders but to build bridges between governments and between peoples."

Trump also threatened to impose an additional 10% tariff on China over the massive amounts of fentanyl coming into the U.S. from Mexico. 

Fentanyl, a synthetic opioid that is up to 50 times stronger than heroin and can be fatal in small doses, has claimed the lives of hundreds of thousands of Americans and is a factor in many drug overdose deaths. 

On Wednesday, Trump said he would be working on a large-scale ad campaign explaining the dangers of fentanyl. 

"Millions of lives being so needlessly destroyed. By the time the Campaign is over, everyone will know how really bad the horror of this Drug is," he said.
