Armenia has a difficult relation with neighbouring countries Azerbaijan and Turkey. Tensions were running high between Armenians and Azerbaijanis during the final years of the Soviet Union. The Nagorno-Karabakh conflict dominated the region's politics throughout the 1990s. To this day, Armenia's borders with Turkey and Azerbaijan are under severe blockade. In addition, a permanent solution for the Nagorno-Karabakh conflict has not been reached despite the mediation provided by organizations such as the OSCE.
