Cuba has firmly rejected talks with the United States after President Donald Trump announced that Venezuelan oil shipments to the island would be stopped.

President Miguel Díaz-Canel said Monday that there are no political negotiations underway with Washington, apart from limited technical discussions related to migration. He accused the U.S. of using threats and economic pressure instead of diplomacy and emphasized that any future talks must respect Cuba’s sovereignty and international law.

“We are open to serious dialogue, but it must be based on mutual respect, equality, and non-interference in our internal affairs,” Díaz-Canel said.

Trump’s announcement comes after a January 3 U.S. operation in Venezuela that led to the capture of President Nicolás Maduro, dramatically reshaping energy and political dynamics in the region. The U.S. move effectively cuts off a key source of oil and financial support for Havana. Trump warned Cuban leaders to reach an agreement with Washington or face consequences.

Cuba has long relied on imported fuel to run its aging power grid. Before the Venezuelan supply disruption, Havana received roughly 35,000 barrels of oil daily from Venezuela, along with smaller amounts from Russia and Mexico. Despite these imports, the island has experienced widespread blackouts due to fuel shortages, hurricane damage, and an aging electrical system.
