"In the run-up to the Normandy Summit, we strongly support Ukraine's sovereignty and its territorial integrity," Nauseda said in a statement to BNS.

"We see Ukraine's leadership and ambition to reach a peaceful solution to the Russia-Ukraine conflict. We hope the Normandy summit on Monday will contribute to ending the war in Donbass," he added.

But the president also stressed that "Russian-backed armed groups are constantly breaking the ceasefire, while Ukrainian troops continue to die in the east of Ukraine, and civilians are also suffering from firings".

"It is essential to maintain international pressure on Russia to fulfill its obligations under the Minsk agreement," Nauseda said.

The summit between Ukraine, Russia, France and Germany will take place in Paris on Monday.
