After the referendum in Crimea on March 16, 2014, the Autonomous Republic of Crimea became a part of the Russian Federation on March 18, 2014. This event incurred a complete change of legislative and regulatory institutions for ports and railways which previously were a part of the Ukrainian state-owned and centrally regulated transport network. Moreover the tensions in the eastern and southern part of Ukraine are threatening the present integrity of the state.
The Ukrainian port system is feeling the full impact of the crisis.
