The United States has announced a new sanctions policy targeting countries that supply oil to Cuba, a move that could have implications for Mexico’s trade posture and regional diplomacy. On January 29, President Donald Trump signed an executive order authorizing tariffs on imports from nations that directly or indirectly provide crude oil to the island nation.
Citing national security concerns, the order declares a state of emergency over what it describes as Cuba’s alignment with hostile actors, including Russia, China, Iran, Hamas, and Hezbollah. The measure accuses Havana of threatening US interests through its foreign alliances and domestic repression. It empowers the US Secretary of Commerce, Howard Lutnick, to identify countries supplying oil to Cuba, while Secretary of State Marco Rubio will determine whether and how steeply to impose tariffs on their exports to the United States.
The policy follows a significant shift in regional dynamics: the US-led capture of Venezuela’s Nicolás Maduro in November 2025. That operation effectively ended Cuba’s primary source of subsidized oil. Washington now appears intent on tightening pressure on Havana by deterring other countries from stepping into Venezuela’s role.
The policy could complicate regional trade dynamics and test Mexico’s balancing act between US alignment and Latin American solidarity.
Mexico is not named in the executive order and currently exports little oil to Cuba. Nonetheless, its historical ties with the island—including limited energy cooperation through state-owned Pemex—place it in a potentially delicate position. While immediate exposure appears limited, any future engagement in oil diplomacy with Cuba could draw scrutiny under the new US framework.
The broader implications extend beyond bilateral trade. The order raises questions about the extraterritorial reach of US sanctions and their compatibility with international trade norms. By threatening tariffs on third-party countries for their sovereign commercial decisions, Washington risks diplomatic friction with regional partners who may view the measure as overreach.
Legal challenges may also emerge. The justification for penalizing countries based on their trade with a third nation—particularly when that trade is not prohibited under international law—could face scrutiny in multilateral forums. Moreover, the durability of the policy remains uncertain. A future US administration may choose to revise or reverse it depending on shifting political priorities.
For now, Mexico appears unlikely to be directly affected. But as Washington expands its use of economic tools to pursue foreign policy goals in Latin America, Mexico and others may be forced to navigate increasingly complex geopolitical terrain.
