Kiev authorities and independence supporters in eastern Ukraine signed on September 5 a ceasefire agreement (the Minsk Protocol) in the Belorussian capital, Minsk, and on September 19 supplemented the document with its detailed implementation plan (the Minsk Memorandum).
"The Ukrainians met in Minsk several times. They signed two documents there, while representatives from Russia and the OSCE have helped them to establish dialogue," Lavrov told reporters on the sidelines of a UN General Assembly session.
