Mykhailo Podoliak, an adviser to the head of the President's Office, told about it, Interfax-Ukraine reports.

"The conversation was quite specific, substantive, covering key topics for our bilateral relations. "The risks of building Nord Stream-2 for European security, the fastest and most effective integration of Ukraine into NATO, the real situation in Donbas without Russian propaganda, the obvious implementation of reforms in Ukraine and, in particular, the process of de-oligarchization", - was informed in the statement.

Also, according to him, "both the President of the United States and the President of Ukraine assess the existing risks to the security of the European region almost equally".

Podoliak also said that "President Biden invited President Zelensky to visit Washington in July after Biden returned from a series of summits in June." "This is a G7 meeting, a NATO summit, a bilateral US-Russia summit", - he said.

"After all these events, it will be quite logical to coordinate the policy of our states again, and once again to conduct and synchronize our partnership positions," the adviser to the head of the President's Office concluded.
