The Mexican government is exploring ways to supply fuel to Cuba to address fundamental electricity and transportation needs while avoiding U.S. sanctions or tariffs, according to a report by Reuters on Tuesday, citing sources familiar with the situation.
Four individuals with knowledge of the negotiations confirmed to Reuters that high-ranking Mexican officials are engaged in discussions with Washington representatives to understand the scope of the executive order signed by President Donald Trump. This order threatens to impose tariffs on nations supplying oil to the island.
According to the sources quoted by the news agency, Mexico is seeking a diplomatic solution that would allow continued fuel shipments by potentially classifying them as “humanitarian aid,” thereby circumventing U.S. sanctions.
The White House, the State Department, and the Mexican presidency have not yet responded to requests for comment. Meanwhile, the Mexican Foreign Ministry informed Reuters that it has no information on the subject.
Cuba relies on imports for about two-thirds of its energy consumption and is currently facing extended blackouts and long lines at gas stations.
Venezuelan oil shipments were halted in December 2025 following the U.S. blockade of Venezuelan tankers and the capture of dictator Nicolás Maduro in January.
Since then, Mexico has become Cuba's main fuel supplier. However, in mid-January, the government led by Claudia Sheinbaum ceased crude and derivative shipments due to U.S. pressure.
The United States views Cuba as an “extraordinary threat” to its national security, a claim rejected by the Cuban regime.
Nonetheless, the threat of sanctions has pushed Mexico to seek a negotiated solution that would allow it to continue its policy of supporting the island.
A source consulted by Reuters mentioned that “there are discussions almost every day” between the two governments, stating that Mexico “does not want to be sanctioned, but also does not want to abandon its policy of solidarity with the Cuban people.”
The media outlet also noted that UN Secretary-General António Guterres warned this week that Cuba risks a "humanitarian collapse" if it does not receive enough fuel to sustain its energy system.
Mexican President Claudia Sheinbaum has publicly defended the delivery of aid and urged against actions that could worsen the crisis.
“Imposing tariffs on countries supplying oil to Cuba could trigger a humanitarian crisis, affecting hospitals, food supply, and other basic services,” said the president last Friday.
Implications of U.S.-Cuba Sanctions
Why is Mexico cautious about sending fuel to Cuba?
Mexico is careful because it aims to avoid U.S. sanctions or tariffs that may be imposed on countries supplying oil to Cuba, as outlined in an executive order by President Trump.
How is Cuba's energy crisis affecting its population?
Cuba is experiencing prolonged blackouts and fuel shortages, which significantly impact daily life, including transportation and basic services.
What role does Mexico play in supporting Cuba's energy needs?
Mexico has become the primary supplier of fuel to Cuba after Venezuelan shipments ceased, although deliveries were recently halted due to U.S. pressure.
