Tensions between Ukrainian President Volodymyr Zelensky and former U.S. President Donald Trump intensified as the United States reached a new diesel supply agreement with Russia, raising concerns in Kyiv about Washington’s commitment to supporting Ukraine amid its ongoing conflict with Moscow.

The discord became apparent after Trump announced the pact to allow diesel exports from Russia to the U.S., a move aimed at lowering domestic energy prices ahead of the November midterm elections. Zelensky condemned the agreement, asserting that it would do little to stabilize global markets while increasing Russia’s revenue to finance its war in Ukraine.

Speaking at a European Union summit in Brussels, Zelensky praised European leaders for their steadfast support, implicitly contrasting their backing with what he described as wavering assistance from the United States. He dismissed Russian President Vladimir Putin’s recent diplomatic overtures as insincere, characterizing them as “parody” and accusing Moscow of playing games in its approach to ending hostilities.

Relations further deteriorated after Trump criticized Ukrainian military actions, specifically the recent bombing of Russian oil refineries, labeling them a “disgrace.” This criticism came amid heightened Russian attacks targeting Kyiv and other Ukrainian cities following the U.S.-brokered temporary reduction in energy-related sanctions.

Ukrainian officials also expressed alarm over disruptions to Starlink satellite services, operated by SpaceX, which have been critical in providing communications and intelligence for Ukraine’s defense efforts. Zelensky indicated that the satellite network’s functionality remained impaired, affecting the military’s ability to intercept Russian attacks. U.S. officials have denied any intentional delay to service restoration, and while Trump stated that intelligence sharing continued, SpaceX CEO Elon Musk clarified that any restrictions on the system’s operation would be controlled by the U.S. government rather than his company.

Additional reports suggest that Trump’s administration is considering easing sanctions on Russia’s so-called “shadow fleet”—a collection of oil tankers that have been blacklisted for obscuring the destination of Russian energy exports. A Treasury Department official confirmed discussions about permitting the sale of these vessels to “legitimate” operators to enable their participation in global markets, a policy shift that could have significant implications for the ongoing conflict.

On a related front, Russia’s presidential investment envoy Kirill Dmitriev disclosed plans for further collaboration between the United States and Russia, aiming to establish joint projects such as data centers powered by Russian nuclear energy. These developments follow the recent diesel agreement and underscore ongoing, albeit limited, economic engagements between the two nations despite strained geopolitical relations.
