Russian President Dmitry Medvedev has arrived Tuesday evening in the city of Astrakhan in south European Russia, where on Wednesday he will meet with the Azerbaijani and Armenian leaders, RIA Novosti reported.
Medvedev, Ilham Aliyev and Serzh Sargsyan are to discuss the resolving of the Armenian-Azerbaijani Nagorno-Karabakh conflict.
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.
