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, who has said the operation against Venezuelan President Nicolas Maduro should serve as a warning to the rest of the world, doubled down on his threats, implying that Colombian President Gustavo Petro could face U.S. action soon.

“Colombia is very sick too, run by a sick man who likes making cocaine and selling it to the United States. And he's not going to be doing it very long. Let me tell you,” Trump claimed while speaking to reporters on Sunday.

Earlier on Sunday, Petro released a statement on the operation and Trump's previous comments about him, saying, "I deeply reject Trump speaking without knowing; my name does not appear in the judicial files on drug trafficking over 50 years, neither from before nor from the present."

"Stop slandering me, Mr. Trump. That’s not how you threaten a Latin American president who emerged from the armed struggle and then from the people’s struggle for Peace in Colombia," he added.

Reporters asked Trump if the U.S. has a similar plan to deal with Cuba as they did for Venezuela, to which he said that Cuba only survived because of Venezuela.

“Now, they won't have that money coming in. They won't have the income coming in. You know, a lot of Cubans were killed yesterday, you know that a lot of Cubans were killed,” Trump said.

Trump said those Cubans were trying to protect Maduro.

Later, the president said that Cuba is “ready to fall.”

“Cuba looks like it's ready to fall. I don't know how they -- if they're going to hold out, but Cuba now has no income,” Trump said. “They got all of their income from Venezuela, from the Venezuelan oil. They're not getting any of it. And Cuba literally is ready to fall. And you have a lot of great Cuban Americans that are going to be very happy about this.”

Asked again if the U.S. is considering action in Cuba, the president said he doesn’t think there needs to be any because “it looks like it’s going down.”
