The Nagorno-Karabakh conflict will be discussed by US Secretary of State John Kerry in Vienna, said John Kirby, the US Department of State assistant secretary and spokesman.
Kerry will travel to Vienna, Austria, May 16-17, Kirby said adding the US, together with Russia and France, will co-host a meeting there on the Nagorno-Karabakh conflict with the Azerbaijani and Armenian authorities.
The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. As a result of the ensuing war, in 1992 Armenian armed forces occupied 20 percent of Azerbaijan, including the Nagorno-Karabakh region and seven surrounding districts.
The 1994 ceasefire agreement was followed by peace negotiations. Armenia has not yet implemented four UN Security Council resolutions on withdrawal of its armed forces from the Nagorno-Karabakh and the surrounding districts.
