Russian President Vladimir Putin is not ruling out talks with Ukraine, but guarantees will be needed to ensure the credibility of any negotiations, Russian news agencies cited Kremlin spokesman Dmitry Peskov as saying on Sunday.
More than 90 countries took part in a two-day event at the Buergenstock resort in central Switzerland aimed at uniting global opinion on how to end Moscow's 27-month-old invasion.
Russia was not invited to those talks.
