Ukrainian Ambassador to the United States Olga Stefanishyna said that after the Ukrainian drone attack on the port in Novorossiysk in November 2025, she received a call from a senior US State Department official. During the briefing, she said that the US State Department complained that the Ukrainian military had damaged the infrastructure of the oil pipeline that pumps American, Kazakh and Russian oil from Kazakhstan to a port in the Black Sea, Suspilne reports..

According to her, the Caspian oil pipeline is one of the largest taxpayers in Russia.

“This concerned the very fact that American economic interests were violated there,” Stefanishina noted..

She was asked why US President Donald Trump reproaches EU countries for continuing to buy Russian oil, but makes an exception for American oil companies. Stefanishina replied that this exception could be revised. In addition, there is a fairly wide variety of options for diversifying supply chains.

“I hope that the initiatives under President Trump's Energy Dominance Doctrine will serve this purpose.. And those unfair situations where we see specific exceptions that ensure US interests can be changed not only by canceling them, but also by changing the structure of the market and supplies,” the ambassador stated.

Let us recall that on November 14, 2025, drones of the SBU and the Ukrainian Defense Forces hit the oil terminal of the Novorossiysk seaport in the Krasnodar region of Russia.

This terminal is the second largest in terms of oil export volumes in the country.. Also serves as a key logistics hub for the supply of petroleum products across the Black Sea.

It is reported that as a result of the attack, oil loading stands, pipelines and pumping equipment were damaged.. There was a large fire at the facility. After the attack, the port stopped oil exports for a certain period, and the monopolist operator of the main oil pipelines of the Russian Federation, Transneft, stopped oil supplies to the port.
