Russian President Vladimir Putin, his Ukrainian counterpart Petro Poroshenko, German Chancellor Angela Merkel and French President Francois Hollande held 16-hour Normandy format talks on Ukraine in the Belarusian capital, Minsk, on Wednesday and early Thursday.
The second document, signed by Normandy Quartet leaders, is a joint declaration in support of the measures agreed upon by the Contact Group.
The Minsk agreements also stipulate the implementation of constitutional reforms in Ukraine, including with the aim of de-centralizing power in the country and giving a special status to some parts of the Donetsk and Luhansk regions.
