In an apparent response to an earlier social media post from President Donald Trump, Cuban President Miguel Díaz-Canel Bermúdez posted on social media Sunday, saying in part "they have no moral authority to point fingers at Cuba on anything, absolutely anything, those who turn everything into a business, even human lives."

He concluded the post, "Cuba is a free, independent, and sovereign nation. No one dictates what we do. Cuba does not aggress; it is aggressed upon by the United States for 66 years, and it does not threaten; it prepares, ready to defend the Homeland to the last drop of blood."

Cuban Foreign Minister Bruno Rodriguez also posted a statement, saying in part, "Like any country, Cuba has the absolute right to import fuel from those markets willing to export it and that exercise their own right to develop their trade relations without interference or subordination to the unilateral coercive measures" of the United States.

President Trump on Sunday posted on his social media platform that Cuba should make a deal with the U.S. “before it is too late," as he attempts to maintain leverage in the region following the raid on Venezuela about a week ago.

President Donald Trump is calling for the country of Cuba to make a deal with the U.S. “before it is too late," as he attempts to maintain leverage in the region following the raid on Venezuela about a week ago.

“THERE WILL BE NO MORE OIL OR MONEY GOING TO CUBA - ZERO! I strongly suggest they make a deal, BEFORE IT IS TOO LATE,” Trump posted to his social media platform.

The call comes after Trump has continued to threaten that the U.S. could take action against Cuba similar to that it took against Venezuela.

Trump had also levied threats against Colombia, but those have been toned down after the country’s president, Gustavo Petro, had a productive phone call with Trump and is set to visit the White House this week.

Trump also claimed on Sunday that most of the Cubans who provide security and intelligence services to Venezuela are “dead” from the United States’ attack to capture Nicolas Maduro on Jan. 3.

“Cuba lived, for many years, on large amounts of OIL and MONEY from Venezuela. In return, Cuba provided “Security Services” for the last two Venezuelan dictators, BUT NOT ANYMORE! Most of those Cubans are DEAD from last weeks U.S.A. attack,” Trump wrote.

The Venezuelan Ministry of Foreign Affairs said the U.S. State Department's security alert is "based on fabricated accounts aimed at creating a perception of risk that does not exist."

The ministry said in a statement on social media late Saturday that Venezuela is "in absolute calm, peace, and stability," and that all weapons are in the government's control.

"The Bolivarian Republic of Venezuela reaffirms its commitment to the protection of peace, institutional stability, and the coexistence of the Venezuelan people," the statement said in Spanish.

The U.S. State Department had earlier warned U.S. citizens in Venezuela to leave immediately, saying in part that there were "of groups of armed militias, known as colectivos, setting up roadblocks and searching vehicles for evidence of U.S. citizenship or support for the United States."

U.S. sanctions on Venezuela are under consideration to be lifted as soon as next week to facilitate oil sales, a senior U.S. official told ABC News Saturday.

The official said Treasury Secretary Scott Bessent has accepted meetings with the heads of the International Monetary Fund and World Bank to discuss their re-engagement with Venezuela.

The official also confirmed roughly $5 billion worth of Venezuela's currently frozen IMF Special Drawing Rights monetary assets could be deployed to help rebuild the country's economy.

"The United States Treasury is fully committed to supporting President Trump's efforts on behalf of the people of Venezuela," a Treasury Department Spokesperson said in a statement to ABC News.

Reuters was the first to report the plans, citing an interview with Bessent.

This comes after President Donald Trump gathered a group of top oil executives at the White House on Friday, aiming to strike a deal for them to invest billions to rebuild Venezuela’s oil industry.

President Donald Trump told reporters on Sunday, “we’re in charge” of Venezuela, doubling down on his claim Saturday that the U.S. will “run” the country.

Trump said that he has not spoken to Delcy Rodriguez, Maduro’s vice president, who was sworn in as interim leader. Asked if he wants to speak to her, the president said, "At the right time, I will."

Trump also said that Rodriguez is cooperating with the U.S., a claim he made Saturday, which she appeared to dispute in an address to Venezuelans, when she called for Maduro’s immediate release.

Later, the president was asked about comments he made to The Atlantic, where he said that if Rodriguez "doesn’t do what’s right, she is going to pay a very big price, probably bigger than Maduro."

Asked what he needs from Rodriguez, Trump called for “total access” to the country’s oil reserves.

“Total access. We need total access. We need access to the oil and to other things in their country that allow us to rebuild their country,” he said.
