"The Summit in Charlevoix and my contacts with the leadership of G7 prior to this meeting confirm that Ukraine remains among key priorities of the Free World," he wrote on Facebook.

"I welcome clear consolidated message of our partners that Kremlin should drop its illusions and implement its commitments in good faith. The conditions are clear: first, respect the international law, stop aggression in the Donbas and return of Crimea to Ukraine. Otherwise, the price for Moscow for its aggression against Ukraine and interference in internal affairs of other states will further increase!" Poroshenko said.
