Mexican President Claudia Sheinbaum says no migrant caravan has reached U.S. since the beginning of President Trump's second presidential term, an apparent attempt to head off a threat by the president to double tariffs if the neighbor country doesn't stop the caravans.

She spoke Thursday, hours after Trump made the threat via social media. 

“Huge CARAVANS are forming and beginning their illegal march through Mexico," he posted. "Many of the people in these Caravans are those that various countries don’t want – ‘Send them to America,’ they say – But they will not be accepted! MEXICO MUST STOP THEM, NOW, and if they do not do so, the Tariffs on Mexico will be IMMEDIATELY DOUBLED,” he wrote on Truth Social.

Sheinbaum in saying that no caravans have reached the countries' border also acknowledged the existence of two of them – one that started in the southern Mexican state of Chiapas with about a hundred migrants now, and another with about 1,500 people, according to Courthouse News Service. 

She also said Mexican officials inform people in caravans that moving to the United States is very difficult and the "vast majority" return to their home countries upon hearing that information. 

Trump tariffs on Mexico now include 25% tariffs on imported passenger vehicles and light trucks, a 50% tariff on steel, aluminum and copper, and 17% tariff on tomatoes. Goods that do not meet rules-of-origin requirements under the U.S.-Mexico-Canada Agreement are also subject to 25% tariffs, the news service also reports. 

Trump issued an executive order  in Jan. 2025 in which he suspended the U.S. Refugee Admissions Program and another that suspended the use of the U.S. Customs and Border Protection’s CPB One app, essentially ending any possibility for refugee or asylum status for illegal migrants coming into the U.S.
