Relations between Ukraine and Russia have not been completely severed by the invasion, Volodymyr Zelensky has suggested.
The Ukrainian President said not all bridges have been "figuratively destroyed", despite Russian troops taking thousands of lives with "torture".
Speaking at a virtual Chatham House event on the 72nd day of the ukraine-crisis>Ukraine crisis, the resolute Ukrainian president hailed civilians who had fought bravely against Russia's aggression.
But he insisted, Ukrainians are not bravely fighting in a "military event", describing the invasion as "torture and hatred" before adding, "it's inhuman and degrading".
Mr Zelensky said arrangements were needed for talks to “stop the killing”, with “diplomatic channels” used to regain Ukraine’s territories.
In an ideal world he wished things could go back to February 23, before Russia's invasion.
“In that situation we will be able to start discussing things normally," Mr Zelensky said.
“In that situation we will be able to start discussing things normally.”
“Despite the fact that they are destroying all our bridges, I think not all the bridges are yet destroyed”, in figurative terms, Mr Zelensky explained.
He opened the virtual event hosted by the Chatham House think tank this afternoon, with upbeat remarks: "My life is really, interesting.
"It is not coming to its end I believe. I believe there’s still a bright future ahead of us. It’s too soon for us to make conclusions to this background."
Classing Russia as a terrorist state he questioned why Putin had threatened to use nuclear weapons across Europe.
"We have to continuously ask for new sanctions against any aggressor. [In this case], Russia is the aggressor.
"What sanctions should we impose in response to the in response to their threats of nuclear weapons?
"The more initiatives we have the more people will get a global scope of answers."
The Ukrainian president believes Russia will soon face a war crime tribunal.
Earlier this week, Amnesty International said it has documented extensive war crimes by Russian forces in communities around the Ukrainian capital Kyiv, including arbitrary killings, bombardments of residences and torture.
After Russian forces retreated from Bucha in April, bodies were found lying on streets, many with their hands bound behind their backs, and in mass graves.
Kyiv regional governor Oleksandr Pavlyuk said that at least 1,235 civilian bodies have been found in the region.
