Mexico-Cuba

Mexico became Cuba's main oil supplier in 2025, overtaking Venezuela after Nicolás Maduro's capture. Pemex sends high-quality light crudes like Istmo and Olmeca, suited to the island's outdated refineries, though this imposes a significant economic cost on the country. President Claudia Sheinbaum has confirmed the shipments will continue as humanitarian aid, despite potential reprisals from Donald Trump.
