Armenia presently maintains good relations with almost every country in the world, with two major exceptions being its immediate neighbours, Turkey and Azerbaijan. Tensions were running high between Armenians and Azerbaijanis during the final years of the Soviet Union. The Nagorno-Karabakh War dominated the region's politics throughout the 1990s. The border between the two rival countries remains closed up to this day, and a permanent solution for the conflict has not been reached despite the mediation provided by organisations such as the OSCE.
