President Petro Poroshenko reminded that 2018 will mark a century since the launch of deep democratic changes not only in Ukraine, but also in Europe. In 1918, as result of downfall of empires, dozens of nations restored or regained their independence. They were the nations of Central Europe, Baltic and Balkan regions. They also were the nations that had been under the rule of the czarist Russia. It was stated by the President in a meeting with the heads of diplomatic missions of foreign states and international organizations accredited in Ukraine.
