Trump’s Tariff Threats Fall Flat for Oil Suppliers to Cuba Amid Russia’s Indifference

Cuba is grappling with its most severe energy crisis in decades, with widespread blackouts, fuel rationing, and the suspension of international flights due to a critical aviation fuel shortage. The crisis has been exacerbated by the U.S. government’s aggressive measures to cut off the island’s access to oil, including the seizure of Venezuelan oil tankers and the imposition of tariffs on countries supplying oil to Havana.

Despite these efforts, Russia has signaled its willingness to continue supporting Cuba, dismissing U.S. threats and positioning itself as a key supplier of humanitarian aid. This dynamic underscores the limitations of Trump’s economic pressure tactics and highlights the geopolitical complexities of the Cuban crisis.

President Donald Trump’s administration has adopted a multifaceted approach to pressure the Cuban government, leveraging the International Emergency Economic Powers Act (IEEPA) to justify its actions. On January 29, 2026, Trump signed an executive order (EO) declaring a national emergency over Cuba’s alleged ‘extraordinary threat’ to U.S. national security. This EO authorizes the imposition of ad valorem tariffs on goods from any country that directly or indirectly provides oil to Cuba.

The EO’s legal basis has been contested, with critics arguing that Trump’s interpretation of IEEPA exceeds his executive authority. A U.S. Supreme Court case, V.O.S. Selections v. Trump, is pending, and the legal debate centers on whether the president has the authority to impose broad tariffs by executive action.

The administration has also relied on the Helms-Burton Act, which codifies U.S. sanctions against Cuba, to justify its economic pressure tactics. However, the effectiveness of these measures remains questionable, as evidenced by the continued flow of oil to Cuba despite U.S. sanctions.

Russia has publicly dismissed U.S. tariff threats, framing its engagement with Cuba as a matter of geopolitical solidarity rather than economic self-interest. According to Kremlin spokesperson Dmitry Peskov, Moscow is ‘actively discussing what help it can provide to fuel-starved Cuba,’ though he emphasized that ‘we don’t have much trade right now.’

Despite this, Russia has signaled its willingness to provide humanitarian aid to Cuba, including crude oil and petroleum products. In February 2026, Russian President Vladimir Putin met with Cuban Foreign Minister Bruno Rodríguez in Moscow on February 18, 2026, reaffirming Russia’s support for Havana and condemning U.S. sanctions as an attempt to ‘suffocate’ the island.

While no oil shipments have been confirmed as of February 20, 2026, Russia’s embassy in Havana has reportedly confirmed plans to send fuel to Cuba as part of a humanitarian initiative.

Cuba’s government has implemented emergency measures to address the energy crisis, including fuel rationing for essential services, the closure of some tourist establishments, and a reduction of the working week at state-owned companies to four days from Monday to Thursday. These measures, while necessary to conserve resources, have further strained an already fragile economy.

The Cuban leadership has warned that international airlines will no longer be able to refuel in the country due to aviation fuel shortages, leading to the cancellation of all flights by Air Canada. The airline subsequently canceled all flights to the island, though it said it would bring some 3,000 customers already in the country back home over the coming days.

The U.S. sanctions have also contributed to the crisis, as Cuba relies on 60% oil imports to meet its energy needs. The loss of Venezuelan oil, which accounted for nearly 90% of its energy imports before the 2025 ousting of President Nicolás Maduro, has left Havana in a precarious position.

The U.S. seizure of Venezuelan oil tankers bound for Cuba has forced the island to seek alternative suppliers, with Mexico now supplying more oil than any other country. The Trump administration has threatened to impose tariffs on Mexican goods if the country continues to supply oil to Havana, creating tension between the U.S. and Mexico with potential implications for the United States-Mexico-Canada Agreement (USMCA).

While the U.S. has framed its sanctions as a means to pressure the Cuban government into political reform, the effectiveness of this strategy remains debatable. Cuba’s leadership has consistently rejected U.S. demands for ‘regime change,’ emphasizing its sovereignty and the right to self-determination.

The Russian response to Trump’s tariffs highlights the limitations of economic coercion in the modern geopolitical landscape. While the U.S. has sought to isolate Cuba economically, Russia’s willingness to provide humanitarian aid suggests that the island remains a strategic player in the region. The Kremlin’s indifference to U.S. threats underscores the broader power dynamics at play, with Russia positioning itself as a counterweight to Western influence.
