BRUSSELS — European Union foreign ministers convened on Tuesday to negotiate the bloc's next sanctions package against Russia, focusing on curbing oil revenues and the so-called shadow fleet of tankers evading Western price caps.

The European Commission has proposed measures targeting additional Russian banks, energy exports and vessels accused of circumventing existing restrictions. Kaja Kallas, the EU's High Representative for Foreign Affairs, has pressed member states to close loopholes she said were sustaining Moscow's war economy in Ukraine. "Every euro Russia earns from oil is a euro spent on the battlefield," Kallas told reporters on arrival at the Council building in Brussels.

Agreement requires unanimity among the 27 member states, and Hungary has repeatedly delayed or diluted previous packages. Diplomats said Budapest raised objections over energy provisions on Tuesday, while Slovakia sought assurances on gas supply, complicating efforts to finalise the text.

The meeting also addressed continued support for Kyiv, including financing and military aid, as Ukrainian officials warned of intensified Russian strikes on energy infrastructure. Ukraine's foreign minister was expected to brief ministers by video link, according to the Council agenda.
