Azerbaijan, Baku, June 29 / Trend E. Mehdiyev /
U.S Deputy Secretary of State William Burns have today met with the OSCE Minsk Group co-chairmen at the U.S. State Department.
The Nagorno-Karabakh issue will be discussed at this meeting. The meeting will be held behind closed doors, the official website of the State Department said on Friday.
The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. Armenian armed forces have occupied 20 per cent of Azerbaijan since 1992, including the Nagorno-Karabakh region and seven 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 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.
