Kremlin says US, Russia agree to hold summit in 'third country'

US President Donald Trump and his Russian counterpart Vladimir Putin will meet in a third country at a date to be announced, the Kremlin said.

Kremlin foreign policy aide Yuri Ushakov said the summit would take place in a mutually-convenient third country and that several more weeks were needed for preparations.

"I can say that we have reached an agreement to hold a summit, we have even agreed on the time and the place of the meeting, and we will announce this obviously with our American colleagues tomorrow," said Russian presidential aide Yuri Ushakov, adding that the meeting would be in a "third country".
