Ukrainian President Volodymyr Zelenskyy met on Thursday with a number of European leaders in Copenhagen at the 7th European Political Community Summit.

In a video shared by Ukrainian Presidential Office, Zelenskyy was seen engaging in talks with French President Emmanuel Macron, German Chancellor Friedrich Merz, Danish Prime Minister Mette Frederiksen, NATO Secretary General Mark Rutte, and others.

After Rutte greeted Zelenskyy with a hug, the Secretary General said, "my favourite president".

At the summit, Macron and other European leaders called for more sanctions against Russia by notably targeting its energy sector.

They said that Ukraine is on the front line of a hybrid war against Europe and underlined the importance of helping the country to defend itself.

Their warnings came at a European Political Community summit in Copenhagen where more than 40 leaders were gathered.

Europe's position on Russia is hardening, Frederiksen said "Russia will not stop until they are forced to do so.”

The summit came after a spate of troubling drone incidents at Danish airports and military bases over the last week. Ahead of the meeting, a special radar system was set up at Copenhagen airport to help keep watch. Unidentified drones forced the closure of the airfield a week ago, causing major disruptions.

France, Germany, the Netherlands, Sweden and the U.K. also sent aircraft, ships and air defence systems to Denmark ahead of the talks. Ukraine’s armed forces dispatched a mission to the Nordic country for joint exercises, sharing its expertise on combating Russian drones.

Leaders and intelligence services believe that Russia could mount an assault elsewhere in Europe in 3 to 5 years, and that President Vladimir Putin is intent on testing NATO as doubts swirl about U.S. President Donald Trump’s commitment to the organization.

On Sept. 10, when several Russian drones breached Poland’s airspace, NATO aircraft were scrambled to intercept and shoot down some of the devices. It was the first direct encounter between NATO and Moscow since Russia launched its war on Ukraine on Feb. 24, 2022.

The incident jolted leaders across Europe, raising questions about how prepared the alliance is against Russia. Days later, NATO jets escorted three Russian warplanes out of Estonia’s airspace.

After Wednesday's meeting began, officials in Germany said that authorities there are also investigating claims that unidentified drones may have spied on a power plant, a hospital and a shipyard in the northern state of Schleswig-Holstein last week.

Turning to Ukraine, the EU leaders discussed ways to maintain military and financial support as the conflict-ravaged country's funds, weapons and ammunition slowly dry up.

A new proposal to use frozen Russian assets to help Ukraine was considered, as well as its prospects of joining the EU. U.S. President Donald Trump has ruled out NATO membership for the country, the best security guarantee available.
