Lavrov and his Japanese counterpart Taro Kono are holding bilateral talks in Tokyo on Friday. Before being joined by their delegations, the two ministers spent more than half an hour talking tete-a-tete.
"I am sure — and hope that today's talks will confirm this — we have something to report to the president and the prime minister when they meet in late June in Osaka," Lavrov said at the beginning of the talks with his Japanese counterpart.

Earlier in May, the Japanese Foreign Ministry said that Tokyo and Moscow were still discussing a possible venue and date for the Putin-Abe summit, with the meeting expected to take place around the time of G20 summit in Osaka, which is scheduled for June 28-29.
Meanwhile, Taro Kono said that positive changes in Tokyo's relations with Moscow had been emerging.
"Despite the fact that only [several] weeks have passed since our previous meeting, some positive shifts in Japan-Russia relations have been emerging," Kono said at beginning of the talks.
"Minister Lavrov, I would like to have frank discussions with you regarding the issue of signing a peace treaty, including joint economic activities on the four Northern Islands, taking into account the Japan-Russia summit in June," Kono said.
