President Donald Trump on Thursday declared a national emergency via an executive order over Cuba, accusing the communist regime of aligning with hostile foreign powers and terrorist groups while moving to punish countries that supply the island nation with oil.

Thursday's executive order states that the policies and actions of the Cuban government constitute "an unusual and extraordinary threat, which has its source in whole or substantial part outside the United States, to the national security and foreign policy of the United States."

To address that threat, Trump ordered the creation of a tariff mechanism that allows the U.S. to impose additional duties on imports from foreign countries that "directly or indirectly sell or otherwise provide any oil to Cuba," according to the order.

The White House said the move marks a significant escalation in U.S. pressure on the Cuban government, aimed at protecting American national security and foreign policy interests.

In the order, Trump said Cuba aligns itself with and provides support for "numerous hostile countries, transnational terrorist groups, and malign actors adverse to the United States," naming Russia, China, Iran, Hamas and Hezbollah.

The administration said Cuba hosts Russia’s largest overseas signals intelligence facility, which the order states attempts to steal sensitive U.S. national security information. The order also says Cuba continues to deepen intelligence and defense cooperation with China.

According to the order, Cuba "welcomes transnational terrorist groups, such as Hezbollah and Hamas."

Trump also cited the Cuban government’s human rights record, accusing the regime of persecuting and torturing political opponents, denying free speech and press freedoms, and retaliating against families of political prisoners who protest peacefully.

"The United States has zero tolerance for the depredations of the communist Cuban regime," Trump said in the order, adding that the administration will act to hold the regime accountable while supporting the Cuban people’s aspirations for a free and democratic society.

Under the order, the Commerce Department will determine whether a foreign country is supplying oil to Cuba, either directly or through intermediaries. The State Department, working with Treasury, Homeland Security, Commerce and the U.S. Trade Representative, will decide whether and how steep the new tariffs should be if so.

Secretary of State Marco Rubio is tasked with monitoring the national emergency and reporting to Congress, while the Commerce Department will continue tracking which countries are supplying oil to Cuba.

In a fact sheet, the White House said the order is designed to protect U.S. national security and foreign policy from the Cuban regime’s "malign actions and policies," and described the move as part of Trump’s broader effort to confront regimes that threaten American interests.

The administration said the action builds on Trump’s first-term Cuba policy, which reversed Obama-era engagement and reinstated tougher measures against the communist government.

The executive order is set to take effect Friday.

The White House did not immediately respond to Fox News Digital's request for additional comment.

China has publicly condemned U.S. pressure on Cuba, accusing Washington of violating international law and calling for an end to sanctions and the decades-long embargo. 

The comments echo Beijing’s long-standing pattern of backing smaller communist governments it says face foreign threats, including Cuba and Venezuela.

"China is deeply concerned about and strongly condemns the U.S. moves, and urges the U.S. to stop depriving the Cuban people of their rights to subsistence and development, stop disrupting regional peace and stability, stop its violations of international law, and immediately lift its blockade and sanctions against Cuba," the Chinese Ministry of Foreign Affairs said in a statement on X on Tuesday morning.

The post was shared by China’s embassy in the U.S.

Beijing has routinely criticized U.S. sanctions policy, framing economic pressure on communist governments as a threat to regional stability.

There is no naval blockade currently in place, though U.S. officials have said it remains an option.

The escalation follows the U.S. capture of Venezuelan President Nicolás Maduro earlier this month, a move that significantly disrupted Cuba’s access to Venezuelan oil and triggered outrage from Havana.

The operation and its fallout marked a dramatic escalation in U.S.–Cuba tensions, with President Donald Trump declaring that Cuba would no longer receive oil or money from Venezuela — a move that severed Havana’s longtime energy and financial lifeline.

Cuban President Miguel Díaz-Canel said his administration was not negotiating with Washington, despite Trump’s threats to push Cuba into a deal now that Venezuelan oil will no longer be supplied.

The Wall Street Journal reported that the Trump administration is actively seeking Cuban officials willing to strike a deal that could facilitate regime change by the end of 2026.

In June, Trump signed a National Security Presidential Memorandum tightening U.S. policy toward Cuba, reinforcing sanctions and travel bans, restricting financial dealings with Cuban military-linked entities, and enforcing the economic embargo.

Cuban President Miguel Díaz-Canel declared Monday that his administration is not negotiating with Washington, despite President Donald Trump’s threats to push Cuba into a deal now that Venezuelan oil will no longer be supplied.

"There are no conversations with the U.S. government, except for technical contacts in the migration field," Díaz-Canel said in a post on X.

Díaz-Canel continued to denounce the U.S., accusing it of applying hostile pressure on the island, and insisted that negotiations would only take place if they are conducted in accordance with international law.

"As history demonstrates, relations between the U.S. and Cuba, in order to advance, must be based on International Law rather than on hostility, threats, and economic coercion," he said.

"We have always been willing to engage in a serious and responsible dialogue with the various governments of the United States, including the current one, on the basis of sovereign equality, mutual respect, principles of International Law, reciprocal benefit without interference in internal affairs and with full respect for our independence," Canel added. 

On Sunday, Trump declared that Cuba would no longer receive oil or money from Venezuela, a move that would sever Havana’s longtime energy and financial lifeline. 

The announcement came after a stunning Jan. 3 operation in Venezuela, in which American forces captured President Nicolás Maduro and reportedly killed at least 32 Cuban personnel.

VENEZUELAN OIL SHIPMENTS SURGE TO US PORTS WITH HEAVY CRUDE AFTER MADURO CAPTURE

"THERE WILL BE NO MORE OIL OR MONEY GOING TO CUBA - ZERO! I strongly suggest they make a deal, BEFORE IT IS TOO LATE," he warned.

Cuba has long depended on imported oil to keep its aging power grid running. Before the U.S. attack on Venezuela, Havana was receiving 35,000 barrels a day from Venezuela, roughly 7,500 from Russia and some 5,500 barrels daily from Mexico, The Associated Press reported, citing Jorge Piñón of the Energy Institute at the University of Texas at Austin, who tracks the shipments.

Even with Venezuelan oil imports, Cuba has suffered widespread blackouts in recent years due to persistent fuel shortages, an aging and crumbling electric grid and damage from hurricanes that have battered the island’s infrastructure.  

Now, with U.S. sanctions tightening on both Russian and Venezuelan oil, blackouts could worsen as Havana’s leaders reject Trump’s call to strike a deal.

Cuban President Miguel Díaz-Canel Bermúdez declared Sunday that the island nation would defend itself "to the last drop of blood," responding to pressure from U.S. President Donald Trump to strike a deal with Washington. 

President Trump had spoken about Cuba in a Truth Social post earlier in the day, urging that "they make a deal, BEFORE IT IS TOO LATE."

"Those who blame the Revolution for the severe economic shortages we suffer should hold their tongues out of shame. Because they know it and acknowledge it: they are the fruit of the draconian measures of extreme strangulation that the U.S. has been applying to us for six decades and now threatens to surpass," the Cuban wrote on X, according to a translation of the Spanish-language 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," he wrote in another post, according to the translation.

Trump declared in a Truth Social post on Sunday, "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, and Venezuela doesn’t need protection anymore from the thugs and extortionists who held them hostage for so many years.

"Venezuela now has the United States of America, the most powerful military in the World (by far!), to protect them, and protect them we will. THERE WILL BE NO MORE OIL OR MONEY GOING TO CUBA - ZERO! I strongly suggest they make a deal, BEFORE IT IS TOO LATE," he warned.
