Russian President Vladimir Putin pledged on Friday to order an immediate ceasefire in Ukraine and initiate negotiations if Kyiv began withdrawing troops from the four regions annexed by Moscow in 2022 and renounced plans to join NATO.
However, such terms are unlikely to be accepted by Kyiv, which seeks NATO membership and demands the withdrawal of Russian troops from all Ukrainian territory.
There was no immediate response from Ukraine to Putin's proposal.
"We will do it immediately," Putin stated during a speech at the Russian Foreign Ministry in Moscow.
Putin's offer comes as leaders of the Group of Seven (G7) met in Italy and Switzerland prepared to host world leaders, excluding Moscow, to discuss peace efforts in Ukraine.
The Russian leader said that the proposal aimed at a "final resolution" of the conflict rather than freezing it, stressing readiness to start negotiations without delay.
His broader demands for peace included Ukraine's non-nuclear status, military restrictions, and protection of Russian-speaking populations.
Putin's conditions included Ukraine recognizing Russia's territorial gains and dropping its NATO bid. He urged for the lifting of all Western sanctions against Russia to restore unity between the two countries and Europe.
World leaders will join Ukraine's President Volodymyr Zelenskiy at the G7 summit in Italy this weekend to explore ways of ending the deadliest conflict in Europe since World War Two, but Russia isn't invited, falling short of Kyiv's aim to isolate Moscow.
U.S. Vice President Kamala Harris, French President Emmanuel Macron, and leaders from Germany, Italy, Britain, Canada, and Japan are among those set to attend the June 15-16 meeting at the Swiss mountaintop resort of Buergenstock.
India, which has aided Moscow during economic sanctions, is expected to send a delegation, along with the presence of Prime Minister Narendra Modi.
Turkey and Hungary, also maintaining cordial ties with Russia, will be represented by their foreign ministers.
Despite intense Ukrainian and Swiss lobbying, some countries will not participate, notably China, a significant consumer of Russian oil and supplier of goods to Russia.
The summit aims to address Europe's deadliest conflict, but without Moscow's involvement.
