MOSCOW, May 21 (Xinhua) -- Russian President Vladimir Putin will be happy to meet his U.S. counterpart Donald Trump on the sidelines of the G20 summit in Japan, but no clear response has been received yet from the U.S. side, Russian presidential spokesman Dmitry Peskov said here on Tuesday.

"Certainly if such a meeting is initiated, our president has already said that he will be happy to hold such a meeting. And, obviously, Europe's energy security issues may be discussed at the meeting," the RIA Novosti news agency quoted Peskov as telling reporters at a briefing.

But he added that no specific steps have been taken to arrange such a meeting between the two presidents.

"We do not yet have information on whether anything at all will be discussed between Putin and Trump at the G20 in Japan," said the spokesman.

Earlier, local reports said that Putin had indicated that Russia was ready to conduct dialogue with the United States at the G20 summit in Japan next month.
