Washington has clarified its concern is about US economic interests, not Russian targets

The US State Department told the Ukrainian government to refrain from hitting US interests following a Ukrainian attack on the Russian port of Novorossiysk on the Black Sea, Kyiv's ambassador to Washington said on Tuesday.

Ambassador Olha Stefanishyna described the message as a demarche, a formal, official message, but declined to elaborate on how it was received and whether she was summoned by the State Department. She said Ukraine had taken note of the communication.

The State Department declined to comment.

Stefanishyna, speaking on the fourth anniversary of Russia's full-scale invasion on Feb 24, 2022, said the State Department reached out after Ukraine's attack on Novorossiysk "because it affected American (and) Kazakh economic interest."

Most of Kazakhstan's oil is sent to Novorossiysk for export. The port halted its November oil exports briefly on Friday after a Ukrainian drone attack.

Stefanishyna said the message focused on strikes affecting US interests, not halting attacks on Russian infrastructure.

"This reach-out was not related to encouraging Ukraine from refraining to attack Russian military and energy infrastructure. It was related to the very fact that American economic interest was affected there," she said.

She said the incident made clear that Ukraine had failed to establish similarly close economic ties with the US in the decades since its independence following the collapse of the Soviet Union, and she was determined to change that.

Her job as ambassador was focused on working with the US to achieve a peace deal, as well as ensuring that Kyiv built sustainable and long-lasting American economic interests in Ukraine, she said, adding this would provide her country with one of the most powerful security guarantees.

Two days of peace talks in Geneva between Ukraine and Russia last week have failed to produce a breakthrough.

NOT FEELING ABANDONED

Stefanishyna, who later attended President Donald Trump's State of the Union address in Congress, said her country was grateful for Trump's personal engagement on ending the war and does not feel abandoned by Washington, despite the failure to reach a ceasefire and his decision to scale back military support.

The ambassador, who served as Ukraine's deputy prime minister for European and Euro-Atlantic integration before going to Washington, urged Congress to pass a comprehensive sanctions bill that would lay the groundwork for further sanctions against Russia, after last year's moves to designate Russia's two largest oil companies, Lukoil and Rosneft.

She said Ukraine was working closely with US lawmakers on the legislation, predicting that it would have overwhelming bipartisan support once introduced, and that she expected Trump to sign it once it passed.

"So it should be either passed now, or we will just have to recognize that there's no will to do it," she said.

Ukraine was also working with the US government on new ways to deprive Russia of revenue to fund the war, but declined to give details.

"There's a number of engagements which are ongoing," she said. "What I can say is that we have not been abandoned by the US government."

Stefanishyna said she expected Trump's address to Congress to touch on foreign affairs and ending Russia's war in Ukraine.
