Presidents of Armenia and Azerbaijan upon Russian President's invitation will arrive in Astrakhan Oct. 27, RIA Novosti quotes the Kremlin's press service today.
"It is planned to discuss issues related to the resolution of the Nagorno-Karabakh conflict during the trilateral meeting," the report said.
Last trilateral meeting was held in St.-Petersburg in July 2010.
The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. Armenian armed forces have occupied 20 percent of Azerbaijan since 1992, including the Nagorno-Karabakh region and 7 surrounding districts.
Azerbaijan and Armenia signed a ceasefire agreement in 1994. The co-chairs of the OSCE Minsk Group - Russia, France, and the U.S. - are currently holding the peace negotiations.
Armenia has not yet implemented the U.N. Security Council's four resolutions on the liberation of the Nagorno-Karabakh and the surrounding regions.
