Cuba is maintaining communication with the United States amid heightened tensions over threats to halt oil supplies. A senior Cuban diplomat confirmed that while exchanges between Havana and Washington continue, they have not yet developed into formal talks. The contact intensified after U.S. President Donald Trump increased pressure on Cuba. Deputy Foreign Minister Carlos Fernández de Cossío told Reuters that the U.S. government is aware of Cuba’s readiness for a serious and responsible dialogue.

The situation escalated following the capture of Venezuelan President Nicolás Maduro, a close ally of Cuba, by U.S. forces and his transfer to the United States. The incident, which also involved Maduro’s wife, has further strained relations and placed the Cuban government under additional U.S. pressure. De Cossío stated that although embassies and diplomatic channels remain active, no formal negotiation framework has been established.

In a separate interview with the Associated Press, De Cossío said that if dialogue begins, it could evolve into structured discussions in the future, but emphasized that Cuba’s constitution, economic system, and socialist governance are not open for negotiation.
