Ukraine is set to call on the European Union next week to take stronger action against Russia, including seizing Russian state assets and imposing new sanctions on buyers of Russian oil, officials confirmed on Thursday.

The push comes amid growing frustration in Kyiv over what it sees as weakening Western resolve. U.S. President Donald Trump has recently backed off from introducing further sanctions on Moscow, shifting the spotlight to Europe to take the lead.

“While Ukraine fights for its sovereignty, Russia continues to profit from energy exports,” a senior Ukrainian official said. “It’s time to strike at the financial sources fueling aggression.”

The proposal includes sanctioning entities that continue to purchase Russian oil through non-transparent arrangements or shadow markets. Ukrainian diplomats argue that stricter financial and energy sector penalties are critical to undermining Russia’s war effort.

The EU has previously implemented 13 rounds of sanctions targeting Russian banks, defense companies, and individuals linked to the war in Ukraine. However, divisions remain within the bloc about escalating economic measures, especially those that could impact global energy markets.

Brussels has not publicly commented on Ukraine’s new requests but is expected to discuss them at a summit early next week.
