Ukraine receives warning from US over strikes on Novorossiysk, Stefanishyna says

Ambassador of Ukraine to the US Olha Stefanishyna said she had received an official warning from the US over strikes on the Russian port of Novorossiysk, which allegedly affected American economic interests.

According to Ukrinform, CNN reported this.

According to the diplomat, the US stated that the strikes on a Russian oil facility in the Black Sea at the end of last year “had impacted US investments in Kazakhstan.”

“We have been hearing that Ukrainian attacks to Novorossiysk affected some of the American investments which are being performed through Kazakhstan. And we have heard from the Department of State that we should refrain from, from, you know, attacking American interests,” Ambassador Olga Stefanishyna said.

She added that she had “received a demarche” from the US Department of State on this issue.

At the same time, the ambassador stressed that the US did not propose that Ukraine refrain from attacks on Russian military and energy infrastructure in general.

“It was related to the very fact that American economic interest was affected there. We have taken the note on that,” Stefanishyna noted.

At the same time, according to her, the letter from the Department of State emphasized that the US does not currently have the same economic interests in Ukraine as it does in Kazakhstan.

“I was really, really sorry that in 35 years of Ukraine independence, having so many chances, we never brought ourselves to the situation where we can do the same,” she stated.

Stephanyishyna called on US lawmakers to pass a law strengthening sanctions against Russia, saying that the delay in its adoption is perceived as a victory for Moscow.

“If we are able to impose more sanctions and more pressure on Russia, they will not be in a position to withdraw from the negotiations,” the ambassador added.

As reported by Ukrinform, at the end of November 2025, unmanned boats cut the mooring system at the Caspian Pipeline Consortium (CPC) Marine Terminal in Novorossiysk, suspending oil shipments.
