John Ratcliffe, the C.I.A. director, is the highest-ranking official in the Trump administration to visit the country.
John Ratcliffe, the C.I.A. director, traveled to Cuba on Thursday, a day after Havana admitted that its fuel oil supplies have been exhausted for consumers and businesses.
Mr. Ratcliffe made the visit to deliver a warning to the government that it had to make economic changes and stop allowing Russia and China to operate intelligence posts in Cuba, U.S. officials said on Thursday.
Mr. Ratcliffe is the highest-ranking Trump administration official to visit Cuba. His trip is part of a multifaceted campaign to escalate pressure against the Communist government and fulfill President Trump’s demand for regime change.
In a statement, the C.I.A. said that Mr. Ratcliffe had traveled to Havana to personally deliver President Trump’s message “that the United States is prepared to seriously engage on economic and security issues, but only if Cuba makes fundamental changes.”
The C.I.A. said Mr. Ratcliffe had met with Raúl G. Rodríguez Castro, known as “Raulito” or “El Cangrejo” (the Crab), the influential grandson of former president Raúl Castro. Mr. Ratcliffe also met with Lázaro Álvarez Casas, the minister of the interior, as well as the head of Cuba’s intelligence services, a C.I.A. official said.
At the same time, federal prosecutors in Miami were working toward securing an indictment of the elder Mr. Castro, who remains a force in the country’s politics, according to several people familiar with the matter. The scope of the indictment and the number of defendants is being debated, but it could include drug trafficking charges and accusations connected to Cuba’s downing in 1996 of planes run by the humanitarian aid group Brothers to the Rescue, two of the people said.
Mr. Ratcliffe arrived in Cuba the day after Vicente de la O Levy, the minister of energy and mines, announced that oil supplies for domestic use and power plants had been exhausted.
“We have absolutely no fuel oil, absolutely no diesel,” he said. “In Havana, the blackouts today exceed 20 or 22 hours.”
The lack of oil has forced people to rely on charcoal or even wood to cook, and some people have taken to the streets, banging on pots and pans to express their frustration.
The Cuban government has been grappling with a severe energy crisis for more than two years because of crumbling infrastructure and a dwindling oil supply from Venezuela, its longtime benefactor.
Venezuelan fuel stopped flowing to Cuba entirely in January, after the United States seized Venezuela’s leader and took control of its oil industry. Later, the Trump administration imposed an effective blockade barring all foreign oil from reaching Cuba, which had also received shipments from Mexico.
A delivery of an estimated 730,000 barrels of oil from Russia last month permitted by the Trump administration provided a brief reprieve.
