"This step shows our commitment to supporting Ukraine's path to EU membership," the EU's Enlargement Commissioner Marta Kos said.

"It would be simply wrong to split us apart on our way into the EU — I hope not. Morally wrong," President Volodymyr Zelensky told EU leaders.

"Without a determined European Union capable of making strong decisions Putin would have gone much further by now," Zelensky said, before calling on the bloc to double down on its support.

"I am standing up for Ukraine's interests solely and the people of Ukraine. We were attacked, we were occupied, our people were killed," Zelensky said when asked to comment on Trump's latest attacks against him.

"We have to classify so that we know how we can shape the support and solidarity with Ukraine in the future," Austria's Chancellor Christian Stocker said.

"I don't like that there are 100 billion euros ($112 billion) from the European budget for Ukraine, that this money should be borrowed," said Czech Prime Minister Andrej Babis.

"We supported Trump's energy ceasefire but we see Russia did not respect it, and so we have to increase the pressure," von der Leyen told journalists, before announcing that the EU is working on a new 22nd package of sanctions against Russia.

The talks apparently failed to yield a breakthrough on the fate of €200 billion ($227 billion) in Russian assets frozen by Euroclear under Belgian jurisdiction.
