Mexican President Claudia Sheinbaum addressed U.S. President-elect Donald Trump's renewed threats of steep tariffs this week, asserting that migrant caravans are no longer reaching the U.S.-Mexico border.

Her remarks underscored growing tensions as Trump plans to tighten immigration policies and impose a 25 percent tariff on Mexican imports. Trump declared that the tariffs would remain in place "until such time as Drugs, in particular Fentanyl, and all Illegal Aliens stop this Invasion of our Country!"

"Caravans of migrants no longer reach the border," Sheinbaum said on Tuesday while presenting a letter she plans to send to Trump in the coming days. She also emphasized Mexico's efforts to curb the flow of drugs, including the synthetic opioid fentanyl, while noting that it remains "a public health and consumption problem within your country's society."

Newsweek reached out to Trump's transition team for comment on Tuesday.
