Twelve leaders from Europe and Canada made their way to Ukraine’s capital on Monday to commemorate the third anniversary of Russia’s invasion, demonstrating solidarity with Kyiv’s key allies during this time of conflict.

The group of visitors, which included European Commission President Ursula von der Leyen and Canadian Prime Minister Justin Trudeau, were warmly received at the train station by Ukrainian Foreign Minister Andrii Sybiha and the president’s chief of staff Andrii Yermak.

In a post on X, von der Leyen wrote that Europe was in Kyiv “because Ukraine is in Europe.”

“In this fight for survival, it is not only the destiny of Ukraine that is at stake. It’s Europe’s destiny,” she wrote.

Attendees, which also comprised European Council President Antonio Costa and the Prime Ministers from Northern European countries and Spain, were scheduled to participate in events observing the anniversary and engage in discussions with President Volodymyr Zelenskyy on how best to support Ukraine, especially given a recent shift in US policy under President Donald Trump.

In the latest sign of Europe’s efforts to rework its strategy on Ukraine to respond to Trump’s actions, Costa on Sunday announced that he would convene an emergency summit of the 27 EU leaders in Brussels on March 6, with Ukraine at the top of the agenda.

“We are living a defining moment for Ukraine and European security,” Costa said in a post on social media.

The three-year mark of the war in Ukraine came at a sensitive moment for Kyiv as Zelenskyy navigates a rapidly changing international environment upended by Trump’s changes to the US approach to the war.

The US leader has sought to follow through on his campaign promises to end the war quickly, though his methods for doing so have alarmed many in Ukraine and Europe who believe that his approach is too conciliatory toward Russia and its president, Vladimir Putin.

Russia’s foreign ministry said Saturday that preparations for a face-to-face meeting between Trump and Putin were underway, and US officials have said that they had agreed with Moscow to reestablish diplomatic ties and restart economic cooperation.

And on Sunday, Russian Deputy Foreign Minister Sergei Ryabkov told the state TASS news agency that Moscow and Washington would continue bilateral talks at the end of next week, adding that “quite a lot” of contact was ongoing between the Russian and American sides.

Leaders across the EU, fearing both that Trump’s approach to Ukraine would lead to an unfavorable settlement for Kyiv and that they — some of Ukraine’s most important supporters — would be sidelined in negotiation for peace, have rushed to assert their own response to the rapidly shifting environment.

The EU’s top diplomat on Monday insisted that the US cannot seal any peace deal to end the war with Putin without Ukraine or Europe being involved.

Kaja Kallas highlighted what she claimed were pro-Russian positions being taken up by the Trump administration.

“You can discuss whatever you want with Putin. But if it comes to Europe or Ukraine, then Ukraine and Europe also have to agree to this deal,” Kallas told reporters in Brussels, where she is chairing a meeting of EU foreign ministers.

Kallas travels to Washington on Tuesday for talks with US Secretary of State Marco Rubio.

Asked whether the US administration is acting in the interests of Russia or Ukraine’s Western backers, she said: “If you look at the messages that come from the United States, then it’s clear that the Russian narrative is there very strongly represented.”

Kallas rejected Trump’s earlier inflammatory assertion that Zelenskyy was a dictator for not having held elections after his regular term expired last year, saying, “Putin hasn’t had elections, or Russia hasn’t had elections, in 25 years.”

Ukrainian law prohibits elections being held while martial law is in place, and Zelenksyy said as recently as Sunday that after martial law is lifted “there will be elections and people will make their choice.”

The UK was expected to announce new sanctions against Russia on Monday, having earlier described them as the biggest package since the early days of the war.

Foreign Secretary David Lammy on Sunday said the measures would be aimed at eroding Russia’s “military machine and reducing revenues fueling the fires of destruction in Ukraine.”

British Prime Minister Keir Starmer and French President Emmanuel Macron were to both visit Washington this week as Europe attempts to persuade Trump not to abandon Ukraine in pursuit of a peace deal.

Meanwhile, Ukrainian air defenses downed 113 drones launched by Russia at 12 regions overnight, with another 71 “lost,” according to the daily Air Force report.

The report said that as a result of the attack, Dnipropetrovsk, Odessa, Kyiv, and Khmelnytskyi regions “suffered,” but did not provide further details.

On Sunday, the eve of the war’s three-year anniversary, Zelenskyy said Russia had launched 267 drones into Ukraine overnight, more than in any other single attack of the war.
