BULBOACA, Moldova: European leaders staged a show of unity in the face of Russia’s aggression against Ukraine and Moldova on Thursday, holding a strategy summit on the continent’s political frontline.

As another deadly Russian missile barrage hit Kyiv, four dozen leaders from across Europe met in Moldova, just 20 kilometers (12 miles) from the border with wartorn Ukraine.

Ukrainian President Volodymyr Zelenskyy arrived first, making the short journey while his capital counted the cost of another night of Russian strikes: three dead, including two children.

Moldovan President Maia Sandu welcomed the leaders to the second summit of the European Political Community (EPC) in the central town of Bulboaca, hoping to boost her country’s bid to join the European Union.

“Ukraine keeps Moldova safe today, and we’re very, very grateful for that,” Sandu told Zelenskyy as the pair met on the red carpet outside the Mimi Castle wine estate.

For the other 47 leaders invited to join them, she had another message: “Please do invest in our countries. Please do believe in our democracies, and in our EU future.”

“This is your contribution to the stability and peace on the continent,” she said.

Zelenskyy thanked Sandu and the Moldovan people, saying Ukrainians were happy to stand “shoulder to shoulder” with them as they seek security guarantees from Europe.

Both Kyiv and Chisinau hope to start EU membership talks this year, despite Moscow’s ongoing invasion of Ukraine and alleged attempts to undermine Moldova’s sovereignty.

The EPC summit was also being held less than 10 km (6 mi) from the breakaway Moldovan region of Transnistria, which is occupied by Russian “peacekeepers.”

The summit was held under tight security, with the North Atlantic Treaty Organization’s (NATO) surveillance planes over neighboring Romania extending cover over the tiny former Soviet republic’s air space.

The EPC groups 27 EU members with 20 of their European allies, and excludes Russia and Belarus.

It is a forum for strategic debate and for some members a potential stepping stone to full EU and or NATO membership, while addressing regional crises.

“We must also think of a wider Europe,” France’s President Emmanuel Macron, who first promoted the idea of forming the EPC, told reporters in Bratislava on the eve of the summit.

“We must think of our Europe not simply from a security point of view within the framework of NATO and not simply within the framework of the European Union,” he said.

The Moldova summit also came as NATO ministers, including US Secretary of State Antony Blinken, met to discuss the agenda of the alliance’s next summit.

The NATO summit in Lithuania’s capital Vilnius on July 11 will debate how formal a promise to give Kyiv on how and when to join the alliance, but in the interim Europe is keen to show support.

Macron said the allies should find a way to offer “tangible and credible security guarantees to Ukraine” while the eventual questions of EU and NATO membership are pending.

United Kingdom Prime Minister Rishi Sunak, whose country left the EU but remains in NATO, said “Putin’s utter contempt of other countries’ sovereignty” showed Europe needed to work together.

EU foreign policy chief Josep Borrell said: “I hope that the presence of so many leaders here, very close to Ukraine, will send a strong message about the unity of many states, not only European Union but others, on defending international order.”

“Russia is not here, not because we don’t want to invite Russia, but because Putin’s Russia has excluded itself from this community by launching this war against Ukraine,” he added.
