Zelensky said Ukraine had always offered solutions for peace and wanted meaningful and honest negotiations on peace and security, without delay.
"I want everyone to hear me now, especially in Moscow. The time has come for a meeting, it is time to talk," he said in a video address released in the early hours of Saturday.
"The time has come to restore territorial integrity and justice for Ukraine. Otherwise, Russia's losses will be such that it will take you several generations to recover."
