HAVANA, Jan. 11 (Xinhua) -- Cuban President Miguel Diaz-Canel on Sunday said Cuba is a free, independent and sovereign nation, rejecting U.S. President Donald Trump's accusations that the island country provided "security services" to Venezuela in exchange for oil.

Diaz-Canel said on X that the United States has "no moral authority to point the finger at Cuba in anything," adding that the U.S. side turns everything, even human lives, into a business.

The president said that the United States is "hysterical" against the Caribbean nation because of the sovereign decision of the Cuban people to choose their political model.

"Those who blame the Revolution for the severe economic hardships we suffer should be ashamed and keep quiet," he said. "Because they know and recognize that they are the result of the draconian measures of extreme asphyxiation that the United States has imposed on us for six decades."

Cuba does not attack or threaten other countries, said Diaz-Canel, adding that the country is ready to defend itself "to the last drop of blood." ■
