Ukraine is working to set up a meeting between President Volodymyr Zelensky and US President Donald Trump, Zelensky said on Tuesday, after giving a speech calling on European leaders to do more to defend the continent.

The Ukrainian leader, speaking at the World Economic Forum in Davos, Switzerland a day after Trump returned to power following months of promises to end the war in Ukraine quickly, also said that a contingent of at least 200,000 European peacekeepers would be needed as part of any settlement to end the war with Russia.

The prospect of a rapid settlement has focused minds in Kyiv and Europe on the urgent need for security guarantees to prevent any future Russian attack, with the idea of peacekeeping contingent force circulating.

“From all the Europeans? 200,000, it’s a minimum. It’s a minimum, otherwise it’s nothing,” Zelensky said when asked about the idea of a peacekeeping mission on an interview panel after delivering his speech.

That number is around the size of the entire French armed forces, estimated at just over 200,000 by France’s defence ministry in 2020. Zelensky said at least that number would be needed as a security guarantee if Russia’s armed forces totalled 1.5 million personnel and Ukraine had only half that number.

Zelensky said such a force would only be part of the security guarantees that Ukraine needed.
