WASHINGTON, August 22. /TASS/. US President Donald Trump does not rule out that a potential meeting between Russian leader Vladimir Putin and Vladimir Zelensky may fail to yield the desired result.

"Look, it takes two to tango. You understand that I wanted to have a meeting with those two. I could have been at the meeting, but a lot of people think that nothing's going to come out of that meeting. You have to be there. Maybe that's true, maybe it’s not," he told reporters at the White House.
