Key players include Mexico's President Claudia Sheinbaum, who vows to continue shipments as humanitarian aid; Pemex, Mexico's state oil company and now Cuba's top supplier (up 20% in 2024 to ~20,000 barrels/day); U.S. President Donald Trump, via his EO declaring a national emergency; and U.S. Rep. Carlos Giménez (R-Fla.), urging Mexico to halt supplies.[1][2][3][4] Cuba's government condemns the EO as a blockade violation.[4]
Cuba's crisis stems from Nicolás Maduro's removal in Venezuela, ending its oil support; Mexico filled the gap, becoming the primary supplier by 2025.[1][2][4] Pemex has supplied Cuba for decades, but U.S. pressure escalated post-EO, with Trump declaring "NO MORE OIL" to Cuba, Navy drone surveillance over Mexican waters, and tariff risks threatening U.S.-Mexico trade ahead of USMCA review.[1][2][3]
Newsworthy due to timing—EO effective January 30, 2026—amid bilateral tensions, potential humanitarian fallout in Cuba (needing ~110,000 barrels/day), and Mexico's vulnerability as U.S. #2 oil supplier.[1][2][3][4][5]
