Russian Foreign Minister Sergey Lavrov today confirmed there while there've been no specific plans for Presidents Putin and Trump to directly talk at next month's Hamburg G20 summit, he assumes they will do so, because they'll both be in the same room at the same time.
The discussion will not have any particular agenda, McMaster said.
Trump will also meet with other world leaders, national security adviser H.R. McMaster said.
"But he also made clear that we will do what is necessary to confront Russia's destabilizing behavior". Trump has staunchly denied that he had any contacts with Russian Federation during his White House bid.
Lavrov said it was especially important that Trump and Putin had an opportunity to talk about the conflict in Syria and efforts to find a peaceful solution.
All 17 USA intelligence agencies have agreed Russian Federation was behind last year's hack of the Democratic Party's email systems and tried to influence the 2016 election to benefit Trump.
McMaster declined to offer further specifics about the meeting, including whether the subject of Russian meddling in the 2016 United States election - confirmed by every U.S. intelligence agency but denied by Russia - might come up.
"It appears that they took the warning seriously", Mattis said, referring to the regime of Syrian President Bashar al-Assad, saying it had not launched any new chemical attacks.
Washington and Moscow engaged in a further verbal escalation after USA fighter jets shot down a Syrian government jet.
The situation in Syria and Ukraine would not be the only issues Putin and Trump might discuss, Lavrov said, adding that the main focus should be on the "normalization" of US-Russia relations. Trump was likely responding to a Washington Post report detailing Obama's response to information about Russian interference in the election.
It was during that call that the leaders agreed to seek a face-to-face meeting in Hamburg.
