The conflict between the two South Caucasian countries arose in 1988 due to the territorial claims of Armenia to Azerbaijan. Nagorno-Karabakh and seven adjacent regions - 20 per cent of the territory of Azerbaijan - are under the occupation of the Armenian Aarmed Forces.
In May 1994, the parties reached a ceasefire, and so far, under the auspices of the OSCE Minsk group and under the co-chairmanship of Russia, France and the United States, peace talks have been unsuccessful.
The four resolutions adopted by the UN Security Council on the liberation of the occupied Nagorno-Karabakh and its adjacent territories are still not implemented by Armenia.
