BERLIN: The European Union is ready to impose tougher sanctions on Russia if progress on ending the war in Ukraine is not made this week, German Chancellor Friedrich Merz said on Tuesday, adding a new package of sanctions was prepared.

鈥淲e are waiting for (Russian President Vladimir) Putin鈥檚 agreement and we agree that if there is no real progress this week, we want to work together at European level for a significant tightening of sanctions,鈥� Merz said at a news conference with his Greek counterpart.

鈥淲e will be looking at other areas, such as the energy sector and also the financial market,鈥� he said.

Merz said EU leaders had agreed with Ukrainian President Volodymyr Zelensky that he could take part in talks with Russia in Istanbul this week on the condition that Russian bombardment and attacks on civilians in Ukraine must stop.

While saying he admired Zelensky鈥檚 willingness to compromise if it could help a ceasefire, Merz added:

鈥淚 believe more compromise and more concessions are no longer reasonable,鈥� said Merz.

Greek Prime Minister Kyriakos Mitsotakis said the EU must be at the center of any peace settlement.
