Ukrainian President Volodymyr Zelensky has said Ukraine must have all Russia-occupied territories back.
"Today, for the sixth year in a row, we are defending our sovereignty from Russian aggression. We pay the highest price for this – the lives of our citizens. Today, the entire civilized world recognizes that Ukraine is doing everything to achieve such a cherished peace. A fair peace. Peace in our understanding of this word. Peace where state sovereignty will prevail in reality, not on paper," he said at a solemn session of the Verkhovna Rada, Ukraine's parliament, on the occasion of the 30th anniversary of the Declaration of State Sovereignty, according to the president's press service.
The president noted Ukraine had lost part of its territory.
"Yes. We lost part of the territory. We lost our people. And, unfortunately, we cannot bring back the dead. But we must return all our territories. Restore faith in truth and justice. So that what our heroes died for never turns out to be useless," Zelensky said.
"I am convinced that we, Ukrainians, have a chance to achieve this only in one case – if we all unite. Just like 30 years ago," he added.
