Tuesday's high-level meeting of the supporter states of Ukraine sends a strong signal of unity, European Commission President Ursula von der Leyen has said.

The agreed joint declaration sends a clear message, she wrote after the discussions in Paris.

Von der Leyen said that collectively, they stand by Ukraine, which continues to fend off a now almost four-year-long full-scale Russian invasion.

The country has a secure, stable and prosperous future ahead, she added.

According to the French government, representatives from more than 30 countries, as well as the EU and NATO, participated in the high-level meeting of the so-called Coalition of the Willing in Paris on Tuesday.
