Ukrainian drones have launched targeted strikes on key Russian oil infrastructure, hitting the Baltic Sea port of Primorsk and the NORSI oil refinery in the central Nizhny Novgorod region. According to Ukrainian drone forces commander Robert Brovdi, these overnight attacks were confirmed by Russian officials on Sunday.In Primorsk, which serves as one of Russia's main oil exporting outlets, Governor Alexander Drozdenko of Russia's northwestern Leningrad region reported that a pipeline was damaged. He later updated that a fuel reservoir in the port area leaked when it was hit by shrapnel.The NORSI oil refinery, Russia's fourth largest, was also targeted. Governor Gleb Nikitin of Nizhny Novgorod stated that a fire broke out at the plant after two facilities were hit. The attack also resulted in damage to a power station and several houses, although there were no reported injuries.These strikes are part of Ukraine's strategy to disrupt Russia's oil infrastructure and reduce a key source of revenue funding Moscow's war efforts. At one point last month, about 40 percent of Russia's oil exporting capabilities were shut down due to these attacks and other disruptions.Diplomatic efforts to end the conflict have stalled, with high-level talks between the US, Russia, and Ukraine yielding no progress on critical issues like territorial concessions in eastern Ukraine.

When the sanctioned Russian tanker Anatoly Kolodkin docked at Matanzas and off‑loaded roughly 700,000 barrels of crude, observers were left questioning why Washington had temporarily lifted its oil embargo on the island.Just weeks earlier, President Donald Trump had taken to social media to declare an end to any oil or cash flowing to Cuba. Yet, in a stark reversal, he later told reporters he had no objection to oil shipments reaching the country, allowing the Russian vessel to pass.Adding to the intrigue, Cuban authorities announced the release of 2,010 prisoners as a “humanitarian gesture” for Holy Week. Analysts quickly linked the pardons to the tanker’s arrival, interpreting both moves as evidence of ongoing, albeit secret, talks between Washington and Havana.The U.S. oil blockade has already pushed Cuba’s fragile economy to the brink: tourism has all but vanished after airlines from Canada, Russia, China and France withdrew, with Iberia set to exit by the end of May. Most petrol stations are shuttered and blackouts have become a daily reality.Population estimates now sit at 9.5 million, down from a pre‑crisis peak after a two‑million‑person exodus over the past five years. Citizens describe a systemic collapse of health, education and transport services.With official channels silent, Cubans are piecing together fragmented leaks—largely from the U.S. side—to gauge the direction of the negotiations.The dialogue pits Trump’s hard‑line rhetoric, which vows to “take” the island, against Cuba’s insistence that its political system is non‑negotiable.One diplomat suggested the tanker’s arrival could be a tactical humanitarian showcase, but also noted it might serve as a confidence‑building measure. The simultaneous prisoner release leans toward the latter interpretation.Professor William LeoGrande of American University observed that such reciprocal gestures often precede substantive diplomatic progress.Meanwhile, another Russian‑flagged tanker, the Sea Horse, carrying about 200,000 barrels, was sighted moving toward Venezuela, hinting at a coordinated “carrot” strategy aimed at both Havana and Caracas.Although oil alone is unlikely to compel the Cuban regime to relinquish power, the recent events suggest a more transactional pathway may be emerging.Since 2021, Cuba has nurtured a private sector of over 10,000 small‑ and medium‑sized enterprises (Mipymes), spawning a new class of affluent Cubans often tied to the regime and the army’s economic arm, Gaesa.Negotiations appear to be led by Raúl Guillermo Rodríguez Castro, a grandson of former President Raúl Castro and son of the late Gaesa chief Luis Rodríguez López‑Calleja.In a recent CNN interview, Fidel Castro’s grandson Sandro Castro, a 33‑year‑old influencer and businessman, argued that the majority of Cubans now favor a capitalist model over communism.His open criticism of President Miguel Díaz‑Canel—calling his performance “unsatisfactory”—would normally trigger state security action, yet appears tolerated, suggesting the U.S. may be leveraging Díaz‑Canel’s vulnerability in the talks.Analysts speculate a possible outcome where Cuba’s economy opens to foreign investment while senior Castros retain political influence, aligning with Trump’s expressed desire for a “friendly” transition reminiscent of recent moves in Venezuela.One senior diplomat in Havana noted that the United States might permit existing private businesses to continue operating, provided they also open markets to U.S. interests.The prospect of any Castro family member retaining authority is likely to provoke fierce opposition from hard‑line Cuban‑American groups, epitomized by figures like Marco Rubio, who have long advocated for the Castros’ removal.Perhaps the greatest concern remains the roughly 40 % of Cubans who are not part of the private sector and rely on state support; many are elderly and now face the very real threat of starvation.

The ongoing conflict between Iran and the US-Israeli alliance has sent shockwaves through global oil markets, with Brent crude prices surging 5% to $106.16 per barrel on Thursday morning. Despite being heavily reliant on Iranian oil, China appears to have largely insulated itself from the crisis.China's strategy involves utilizing 'teapot refineries,' small, privately owned oil refineries primarily based in Shandong province. These facilities have been importing discounted Iranian and Russian oil, accounting for one-quarter of China's processing capacity. This approach allows China to circumvent US sanctions and maintain a stable oil supply.China's teapot refineries have been stockpiling oil reserves, providing a buffer against potential supply disruptions. According to Muyu Xu, a senior crude oil analyst at Kpler, China's seaborne crude imports in March stood at 10.19 million barrels per day (mbd), down from 11.51mbd in February but still in line with the 2025 average of 10.41mbd.The US has previously imposed sanctions on some of these teapot refineries for importing Iranian oil. However, China's tolerance of this independent system has proved strategically useful, allowing the country to maintain a flexible buffer for bargain barrels during crises.Experts note that while China's measures will not completely immunize the country from rising fuel prices, they do provide Beijing with more flexibility to survive a crisis compared with other nations. China's approach involves aggressive stockpiling, tolerating shadow networks, and keeping flexible buffers, demonstrating its preparedness for energy shocks.

Ukraine is facing a critical spring as the country's situation continues to deteriorate. US financial support has dried up under Donald Trump, making European aid crucial. However, Hungary's Prime Minister Viktor Orbán is blocking a €90bn EU loan to Kyiv, causing exasperation for Ukrainian President Volodymyr Zelenskyy.Orbán's opposition is driven by his nationalist base and allegations of collusion with Russia to undermine European decision-making. With US attention shifting to the Middle East, Ukraine has become more vulnerable and reliant on European support. Higher oil prices and the lifting of restrictions on Russian oil have boosted Vladimir Putin's war economy, while stocks of US Patriot missile interceptors are dwindling.Meanwhile, peace negotiations with Moscow have paused, and the White House's priorities in the Gulf are taking precedence over Kyiv's needs. Ukraine's president has stated that future US security guarantees are being linked to the surrender of unoccupied territory in the Donbas. Europe must develop stronger mechanisms to counter blocking tactics like Orbán's and provide crucial financial support to Ukraine.

Ukrainian unmanned aircraft have targeted the Russian Baltic port of Ust‑Luga for the fifth time within a ten‑day span, intensifying Kyiv's campaign against Russia's oil‑export infrastructure. Regional governor Alexander Drozdenko reported that three individuals, two of them children, received medical care after the latest overnight raid, and several structures sustained damage. He added that regional air‑raid alerts have since been lifted, though details on port damage remain scarce. Located on the southeastern coast of the Gulf of Finland, Ust‑Luga comprises an extensive network of oil‑processing plants and export terminals. The facility moved 32.9 million metric tonnes of oil products in the previous year and typically handles around 700,000 barrels of crude oil per day. The series of strikes on March 22, 25, 27, 29 and 31 forced temporary suspensions of export operations. According to market‑based calculations, the cumulative effect of drone attacks, a contested pipeline strike and the seizure of tankers has halted roughly 40 % of Russia's oil export capacity. The disruption has contributed to a surge in global oil prices, with Brent crude climbing above $116 a barrel – its highest level in nearly two weeks amid escalating conflicts involving the United States, Israel and Iran. While Kyiv continues to press its aerial campaign, the European Union dispatched senior diplomats, including top envoy Kaja Kallas, to the Ukrainian capital. Their visit, timed with the fourth anniversary of the Bucha massacre, underscored EU commitment to holding Russia accountable for alleged war crimes. Kallas posted on X, describing Bucha as a symbol of Russian brutality, and affirmed that the EU will not allow such atrocities to go unpunished. Ukrainian Foreign Minister Andrii Sybiha echoed the message, urging international partners to keep their focus on Ukraine despite the widening war in the Middle East. Financially, the EU’s planned €90 billion loan for Ukraine has been stalled by Hungarian Prime Minister Viktor Orban, who objects to Russia's oil transit through the Druzhba pipeline and is also impeding Ukraine's EU accession talks. In parallel, Kyiv announced that its air‑defence forces intercepted 267 of 289 Russian drones launched overnight, while Russian officials claimed control of the village of Mala Korchakivka in the Sumy region. The convergence of intensified drone attacks on Russian oil assets, soaring energy prices, and high‑level EU diplomatic activity highlights the expanding geopolitical ripple effects of the Ukraine conflict across Europe and the broader Middle‑East theater.

Donald Trump has indicated a shift in his administration's stance on oil shipments to Cuba, stating that he has 'no problem' with countries sending oil to the island, whether it's Russia or not. This development comes as a Russian oil tanker, under US sanctions, was set to arrive in the Caribbean island. The Russian tanker, Anatoly Kolodkin, carrying 730,000 barrels of crude, could soon discharge at Cuba's Matanzas port. This shipment would provide significant relief to Cuba, which has not received any oil imports for three months, leading to strict rationing of gasoline and exacerbating an energy crisis that has resulted in multiple power outages across the island. Cuba lost its main regional ally and oil supplier in January when US forces captured Venezuela's president, Nicolás Maduro. Trump subsequently threatened to impose tariffs on any country sending oil to Cuba and has mused about 'taking' the island. The US oil blockade has forced Cuba to impose emergency measures to conserve fuel, including strict rationing of gasoline. Fuel prices have soared, public transport has dwindled, and some airlines have suspended flights to Cuba, hitting the country's fragile economy. Jorge Pinon, an expert on Cuba's energy sector at the University of Texas at Austin, noted that once the Russian tanker enters Cuban waters, it 'is almost impossible for the US government to stop it.' The Russian shipment could be converted into 250,000 barrels of diesel, enough to cover the country's demand for about 12.5 days, according to Pinon.

The UK government has taken a significant step in its ongoing efforts to counter Russia's attempts to evade Western sanctions. Armed forces have been authorized to board Russian oil tankers in British waters, a move aimed at disrupting Moscow's 'shadow fleet' of vessels.This fleet, comprising over 600 vessels targeted by sanctions from the EU, UK, and US, uses tactics such as false national flags and opaque ownership structures to export Russian crude oil while avoiding Western sanctions. The new rules apply specifically to vessels sanctioned by the UK.The Royal Navy has previously collaborated with allies to take action against these vessels. For instance, last week it helped track a sanctioned Russian oil tanker in the Mediterranean, which was subsequently boarded by the French navy.The UK's move is part of a broader strategy to hamper Russia's economy and, consequently, its war efforts in Ukraine. Prime Minister Starmer emphasized that the goal is to 'starve Putin's war machine of the dirty profits that fund his barbaric campaign in Ukraine.'However, Russia has warned that direct action against shadow fleet vessels could lead to direct conflict. A senior Russian official, Nikolai Patrushev, suggested that Moscow could deploy its navy to protect Russian-linked vessels from potential European seizures.The UK's defense secretary, John Healey, previously suggested using 'military options' against sanctioned vessels, with any seized oil potentially being sold and the proceeds sent to Ukraine.Before any ship is boarded, its situation will be examined by law enforcement, military, and energy market specialists, with a recommendation made to ministers. Seizure could be followed by criminal proceedings against the owners, operators, and crew for breaches of UK sanctions legislation.
