Cuba rejects Trump's deal demands as Venezuelan oil lifeline ends. President Díaz-Canel says no negotiations with Washington despite energy crisis threats.

Cubans are bracing for impact after U.S. President Donald Trump vowed to cut off a lifeline of Venezuelan oil from reaching Cuba, setting up a siege scenario for an island already reeling from crippling blackouts and shortages.

Mexico, which was providing some oil to Cuba before Maduro's capture by the U.S., has become an especially key fuel supplier to the island since the Venezuelan leader's arrest, which was accompanied by the U.S. interception of vessels carrying oil to Cuba. Sheinbaum has referred to oil as "humanitarian aid."

HAVANA/HOUSTON, Jan 11 (Reuters) - U.S. President Donald Trump on Sunday said no more Venezuelan oil or money will go to Cuba and suggested the Communist-run island should strike a deal with Washington, ramping up pressure on the long-time U.S. nemesis and provoking defiant words from the island's leadership.

President Donald Trump has urged Cuba to make a deal with the U.S. as he uses Venezuela to crank up the pressure on the island.
