Sheinbaum hardens stance on U.S. custody deaths, Cuba sanctions pressure

Mexico’s clash with Washington hardened after the death of 49-year-old Alejandro Cabrera Clemente in an ICE detention center in Louisiana, the 15th death of a Mexican citizen in U.S. custody in a little over a year. Claudia Sheinbaum said she had asked for investigations into all 15 deaths and ordered Mexican consulates to visit detention centers every day, a sign Mexico was no longer content to issue cautious complaints while deaths kept piling up.

Mexico called the detention centers “unacceptable” and “incompatible with human rights standards and the protection of life.” Sheinbaum said her government would defend Mexicans “at every level,” and Mexico said it would back lawsuits in U.S. courts over poor detention conditions, take the cases to the Inter-American Commission on Human Rights and consider turning to the United Nations. The message was blunt: migrants held without papers, Mexico argued, are still under Mexico’s protection.

The tougher line matters well beyond the border. It comes after more than a year in which Sheinbaum largely kept a measured tone with Donald Trump while Mexico cooperated with U.S. demands to crack down on criminal cartels under threats of tariffs and possible military action. Now, with anger over custody deaths rising inside Mexico and criticism of ICE growing inside the United States, Sheinbaum has more room to push back. Palmira Tapia of the Center for Economic Research and Teaching said she had “raised her tone,” while Carin Zissis of the Council of the Americas said dissatisfaction in the United States over ICE activity has opened more space for Mexican officials to object.

The Cuba piece is where the pressure gets real for Havana. Trump’s sanctions campaign has kept Cuba in the crosshairs, and Sheinbaum has described it as “unjust” and said Washington was “suffocating” Cubans. Mexico has been one of Havana’s most important friends, and Mexican oil shipments became a vital lifeline after Venezuelan supply disruptions hit the island. But Mexico was already reviewing whether to keep sending oil because of fear of U.S. retaliation, and later canceled at least one shipment under that pressure.

That leaves Sheinbaum balancing two fronts at once: defending Mexicans caught in U.S. custody and preserving Mexico’s leverage with Havana without triggering a direct fight with Washington. For Cubans, the stakes are immediate. If Mexico pulls back further, the margin for fuel imports narrows, and Havana’s room to maneuver gets tighter at the same time migration pressure and sanctions pressure are both rising.
