Europe and Russia are butting heads over who should join the next round of Ukraine peace talks.
The US said Europe would be involved, but Russia quickly pushed back, saying nothing's settled yet.
All this back-and-forth is making the future of these negotiations pretty uncertain.
EU leaders insist on Ukraine involvement
European leaders say they need to be part of any deal about Ukraine.
German Chancellor Friedrich Merz called Russia's hesitation just a tactic, insisting that Europe's involvement is crucial.
European Commission President Ursula von der Leyen echoed this at a Dublin summit, saying Europe has to protect its own interests and support Ukraine.
Meanwhile, EU top diplomat Kaja Kallas reminded everyone not to get sidetracked by bigger demands from Russia: her focus is on getting a ceasefire first as leaders rush to pick their negotiator.
