Speaking at the White House, Trump said previous administrations had considered action against Cuba for decades and suggested he could be the president to pursue it. While he did not outline specific plans, his remarks marked the latest escalation in Washington’s rhetoric toward the communist-run island.

Rubio, speaking separately in Miami before departing for meetings in Europe and India, said the administration’s preferred outcome remained a negotiated settlement but acknowledged doubts that meaningful progress could be achieved with Cuba’s current leadership.

“The president’s preference is always a negotiated agreement that’s peaceful,” Rubio said, adding that prospects for such an outcome were limited given the current political environment in Havana.

The comments came one day after U.S. federal prosecutors announced an indictment accusing Castro of ordering the 1996 shootdown of civilian aircraft operated by Cuban exiles based in Miami. The charges include murder and destruction of an aircraft. Cuban authorities have rejected the case, with Cuban President Miguel Díaz-Canel describing it as a political maneuver intended to justify potential aggression against the island.

The indictment has fueled speculation that the Trump administration may be considering a more confrontational approach toward Cuba. Analysts have drawn comparisons to Washington’s earlier operation against Venezuelan leader Nicolás Maduro, who was captured by U.S. forces earlier this year and faces federal criminal charges in the United States.

Senior U.S. officials, including Rubio and CIA Director John Ratcliffe, have held discussions with Cuban representatives in recent months aimed at improving relations. Rubio said those contacts failed to produce meaningful results and contributed to the administration’s decision to impose additional sanctions on Havana.

Among the latest measures are sanctions targeting Grupo de Administración Empresarial S.A., a business conglomerate controlled by Cuba’s armed forces. Rubio also announced that a relative of the group’s executive president had been detained by U.S. immigration authorities after her legal residency status was revoked.

The administration argues that Cuba presents a national security challenge because of its security and intelligence ties with China and Russia, as well as its relationships with governments viewed as adversarial by Washington.

China rejected the U.S. position on Thursday. Foreign Ministry spokesman Guo Jiakun said Beijing supports Cuba’s sovereignty and opposes external interference and sanctions.

The heightened tensions come as the U.S. military conducts exercises in the Caribbean involving the aircraft carrier USS Nimitz and accompanying vessels. U.S. Southern Command said the deployments are part of previously scheduled maritime operations with regional partners.

Trump has increasingly linked future relations with Cuba to demands that Havana expand economic openness and reduce ties with U.S. geopolitical rivals, while continuing to tighten sanctions pressure on the island’s government.

The charges announced by U.S. authorities on Wednesday intensified tensions between Washington and Havana and prompted criticism from Beijing, which reaffirmed support for Cuba’s sovereignty and opposition to foreign interference.

“The U.S. side should stop brandishing the sanctions stick and the judicial stick against Cuba and stop threatening force at every turn,” Chinese foreign ministry spokesman Guo Jiakun told a regular press briefing in Beijing.

“China firmly supports Cuba in safeguarding its national sovereignty and national dignity and opposes external interference,” Guo said.

The indictment against Castro, 94, includes charges of conspiracy to kill Americans and destruction of aircraft linked to the 1996 shooting down of two planes operated by anti-Castro activists, an incident that killed four people.

Castro, the younger brother of late Cuban revolutionary leader Fidel Castro, led Cuba from 2008 until 2018 after decades as one of the country’s most powerful political figures.

U.S. President Donald Trump described the indictment as a “very big moment” on Wednesday but downplayed suggestions of immediate action against the Cuban government.

The development comes as Cuba faces a prolonged economic crisis marked by fuel shortages, inflation and declining foreign currency reserves, conditions Havana has blamed in part on longstanding U.S. sanctions and restrictions.

China has maintained close political and economic ties with Cuba and has consistently criticized Washington’s sanctions policy toward the island nation.

The investigation focuses on Operation Southern Spear, a campaign launched by the administration of US President Donald Trump in September 2025 targeting boats Washington alleges are linked to narcotics trafficking networks operating from Latin America.

According to reports, the Pentagon review will examine whether the US military followed established operational and legal procedures under the Joint Targeting Cycle, the framework governing the planning and execution of military strikes.

“The scope of this evaluation includes the joint process for targeted vessels in the US Southern Command area of responsibility as part of Operation Southern Spear,” the Pentagon inspector general’s office said in a memorandum cited by Bloomberg.

The review will be conducted at the Pentagon and at the headquarters of United States Southern Command in Florida, according to the memorandum dated May 11.

The military campaign has drawn criticism from legal experts and human rights organizations, which argue the strikes may constitute extrajudicial killings because the targeted vessels allegedly did not pose an imminent threat to the United States.

Critics have also questioned whether the administration has provided sufficient evidence demonstrating that the vessels destroyed during the operations were actively involved in drug trafficking.
At least 192 people have reportedly been killed since the start of the operation, according to media accounts cited in the reports.

US Defense Secretary Pete Hegseth has defended the campaign, describing the operation as part of a broader war against what the administration terms “narco-terrorists.” Hegseth previously said the operation had been so aggressive that potential maritime targets had become increasingly difficult to locate.

The strikes represent a significant shift in US counter-narcotics strategy. Historically, American anti-drug operations in the region have focused on intercepting vessels, seizing narcotics shipments and arresting suspects rather than conducting lethal military attacks at sea.

The growing scrutiny comes as the Trump administration continues expanding military involvement in transnational security operations across Latin America and the Caribbean.

The aircraft arrived Thursday at Piarco International Airport from the Bahamas for refueling before continuing onward to Libya through Cape Verde, according to the Airports Authority of Trinidad and Tobago.Immigration officials inspecting the aircraft found explosives onboard that had not been disclosed in accordance with international aviation and security procedures, the airport authority said in a statement.

Authorities detained the aircraft temporarily while conducting inquiries into the cargo documentation and security compliance. Officials later concluded that the crew and pilot bore no responsibility for the undeclared shipment.

“It was determined that no liability should be attributed to the pilot or crew,” the Airports Authority said, adding that the aircraft and personnel were subsequently authorized to leave Trinidad and Tobago.Officials did not specify the type or quantity of explosives being transported, nor did they disclose the aircraft’s ownership or final recipient in Libya.

Trinidad and Tobago, located off Venezuela’s northeastern coast, has long faced scrutiny from regional security agencies over narcotics trafficking and organized crime activity. The government has declared multiple states of emergency since 2021 in response to rising violent crime rates.

The incident comes amid heightened international monitoring of aviation cargo movements involving sensitive materials across conflict-linked transit routes.

UNESCO is expanding efforts to protect living heritage across Small Island Developing States (SIDS), arguing that traditional knowledge systems are increasingly essential to disaster preparedness and climate resilience as island nations face rising environmental threats.

From the Pacific to the Caribbean, communities are using inherited practices such as cyclone-resistant housing, traditional medicine, oral storytelling, food preservation and weaving not only to preserve cultural identity, but also to respond to increasingly severe climate pressures including rising sea levels, volcanic activity, floods, cyclones and displacement.

UNESCO said these practices, often passed down through generations, represent both vulnerable cultural assets and practical tools for survival, particularly in remote communities with limited access to formal infrastructure.

Small Island Developing States account for less than 1% of global greenhouse gas emissions, yet remain among the most exposed to the consequences of climate change because of their geography, dependence on natural resources and vulnerability to extreme weather events.

In response, UNESCO, with financial support from the Government of Japan, launched a regional project involving communities in Fiji, Tonga, Vanuatu, Belize and The Bahamas to strengthen the role of intangible cultural heritage in disaster risk reduction.

The project focused on documenting community practices, supporting transmission of traditional knowledge and connecting local communities with disaster management authorities so cultural knowledge could be integrated into formal resilience planning.

UNESCO said the approach reflects a broader recognition that living heritage can serve as both a safeguard and a response mechanism during emergencies.On Vanuatu’s Tanna Island, for example, community member Warau Frederick described traditional cyclone shelter construction as both cultural preservation and physical protection.

Vanuatu is among the countries most exposed to climate-related disasters in the Pacific, regularly facing cyclones, volcanic eruptions and displacement pressures. Communities there continue to rely on long-established building methods using local materials and inherited techniques to construct shelters capable of withstanding severe weather.

Frederick said he learned the process from his uncle and chose to build a shelter for his family before cyclone season, reflecting how traditional architecture remains embedded in everyday preparedness.Traditional weaving also remains economically significant in the same communities.

Eva Namri, a community member on Tanna Island and a knowledge bearer of traditional weaving, said the practice serves as a financial safety net during periods of hardship.“Weaving brings a great deal of income to my family,” Namri said. “It supports us whenever we face financial difficulties.

The biggest challenge for weaving comes from natural disasters.”UNESCO said such examples show how cultural practices operate simultaneously as economic resilience tools and heritage systems, particularly where formal income opportunities are limited.

Across the Caribbean, communities participating in the project focused on preserving food systems and traditional medicine as part of local resilience strategies.

In Fiji, where flooding and environmental changes increasingly threaten food security, communities relied on traditional fishing, farming methods and collective cooperation to maintain access to food.

In Vanuatu, people facing repeated displacement from volcanic activity and cyclones used early warning knowledge, gardening systems and traditional housing practices to reduce vulnerability.In Tonga, communities displaced by a volcanic eruption and tsunami emphasized the importance of oral traditions and craft practices not only for cultural continuity but also for mental well-being and livelihood recovery after disaster.

UNESCO said the project also created longer-term institutional foundations by identifying community members to serve as Intangible Cultural Heritage ambassadors, responsible for helping sustain and transmit traditional practices beyond the duration of the program.These local ambassadors were tasked with ensuring knowledge transfer, particularly in communities facing relocation or demographic shifts that risk interrupting intergenerational learning.

For many participants, the initiative also had direct economic implications.Feleti Akauola, a community member from Atata in Tonga, said relocation after disaster created uncertainty over how families could rebuild sustainable livelihoods.

He said guidance from Sitiveni Fehoko, a community trainer and intangible cultural heritage ambassador, helped communities think about traditional knowledge not only as preservation, but as a source of income and long-term stability.

“One of the key aspects of the project was that it strengthened me in many ways,” Akauola said. “It explained ways we could earn a living, especially for those of us who had been relocated. This was very encouraging, and it gave me and my wife the idea to start our work and make a living for our family.”UNESCO said this illustrates how cultural safeguarding increasingly intersects with economic adaptation, particularly in island states where environmental shocks can quickly translate into displacement, unemployment and food insecurity

.The agency has argued that disaster planning should not treat heritage solely as something to be protected after crisis, but as an active component of prevention and recovery strategies.As climate risks intensify globally, UNESCO said living heritage offers continuity that extends beyond formal emergency responses, helping communities retain identity while adapting to rapidly changing environmental conditions.

The organization said the project also raised awareness of vulnerable traditions that may otherwise disappear as migration, urbanization and repeated disasters disrupt local transmission systems.Even in cases of displacement, UNESCO found that communities continued practicing oral traditions, crafts and local environmental knowledge, reinforcing the adaptability of living heritage under pressure.

The initiative aligns with broader United Nations Sustainable Development Goals related to climate resilience, cultural sustainability and inclusive development, particularly in regions where environmental vulnerability and cultural preservation are closely linked.UNESCO said future efforts will continue to focus on integrating heritage protection into national disaster reduction policies while supporting local ownership of cultural safeguarding.

For Small Island Developing States, the agency said, resilience increasingly depends not only on infrastructure and funding, but also on whether communities can retain the knowledge systems that have helped them survive for generations.

Speaking to reporters aboard Air Force One, Trump said Washington would not oppose a shipment from Russia or other countries if intended to alleviate shortages. “If a country wants to send some oil into Cuba right now, I have no problem whether it’s Russia or not,” he said.

Shipping data cited in reports shows a tanker carrying roughly 730,000 barrels of oil nearing Cuba’s eastern coast, with an expected arrival in Matanzas. The vessel is expected to deliver fuel that could yield about 180,000 barrels of diesel, enough to meet the country’s demand for more than a week.

The tanker, identified as the Anatoly Kolodkin, is under sanctions imposed by the United States, the European Union and the United Kingdom following the war in Ukraine.

Trump’s remarks come despite his administration’s intensified efforts to restrict oil flows to Cuba in a bid to pressure its government. He has previously threatened punitive tariffs on third countries supplying oil to the island.

The blockade has contributed to widespread fuel shortages, with reports of prolonged blackouts and disruptions to public transport and healthcare services across Cuba.Cuba has long been a focal point of strategic competition between the United States and Russia.

Trump dismissed suggestions that allowing the shipment would benefit Russian President Vladimir Putin, saying the delivery would have limited impact beyond addressing immediate needs.

He said he would prefer allowing fuel deliveries to ease hardship for civilians, citing the need for electricity, heating and cooling as essential services.
