Paris is expected to host the emergency summit following US President Donald Trump's direct talks with Russia to end the Ukraine war.
Trump shocked European leaders on Wednesday when he said he had spoken to Putin and ordered talks on Ukraine to begin "immediately."
The announcement spread fear among European leaders that they would be excluded from the negotiations to end the war.
The subject was at the top of the agenda at a three-day security meeting in Munich that opened on Friday.
The conference played host to meetings of US and Ukrainian officials, including a sit-down between Vice President JD Vance and President Volodymyr Zelensky.
Speaking after the meeting with Vance, Zelensky called on Europeans to "act for your own sake" in the face of the threat from Russia.
"Europe just needs to come together and start acting in a way that no one can say no to Europe," Zelensky said.
Separately, the EU's foreign policy chief Kaja Kallas called a meeting of foreign ministers from the bloc at the conference for Sunday morning.
