Leaders of the 'Normandy Four' member countries (France, Germany, Ukraine and Russia) will meet this summer, Ukrainian First Deputy Foreign Minister Vadym Prystaiko said.

"Negotiations are in progress, and I cannot endanger them by telling you the approximate date right now. Everything will happen much faster than before the end of this summer," Prystaiko told Interfax-Ukraine on Wednesday, replying to the question regarding the date of a possible meeting between the 'Normandy Four' leaders.

French President Emmanuel Macron said after he had met with Russian President Vladimir Putin on May 30 that the 'Normandy Four' negotiations should be held as soon as possible.
