"We hope that such a meeting will take place, but there can be lots of questions because it can be an on-the-go meeting, a very brief one; it can be a meeting on the sidelines [of the G20 summit]; or it can be a pre-planned full-scale meeting with an agenda, which, maybe, would be more necessary, based on common interests", Peskov told the Rossiya 1 broadcaster.
The spokesman also noted that Moscow was waiting for Washington to come up with initiatives regarding the possibility of the Putin-Trump meeting, but no proposals had been made by the United States so far.
Peskov added that it was difficult to talk about the prospects of Russian-US relations in light of the upcoming presidential election campaign in the United States, but certain things would clear up at the G20 summit.
