- Beginning from the very first day of the cooperation the United Nations drew the international community’s attention to the Armenia-Azerbaijan conflict and during 1993 the UN Security Council adopted four resolutions 822, 853, 874 and 884 on the Armenian-Azerbaijan conflict. Each of the abovementioned resolutions was adopted following the subsequent occupation of Nagorno-Karabakh region and other territories of the Republic of Azerbaijan by the Armenian armed forces. These resolutions reaffirmed the territorial integrity of Azerbaijan, demanded immediate cease-fire, suspension of hostilities and withdrawal of all occupying forces from the territory of the Republic of Azerbaijan. Regrettably, the provisions of the resolutions have still not been implemented.

            The main role in the settlement of the conflict has being performed by the OSCE. At the OSCE Lisbon Summit, which took place on 2-3 December 1996, the following principles of settlement of the Armenia-Azerbaijan conflict were recommended by the CSCE chairman-in-Office and Co-Chairmen of the Minsk Group and supported by all the OSCE Member States except Armenia:

     - territorial integrity of the Republic of Armenia and the Azerbaijan Republic;
     - legal status of Nagorno-Karabakh defined in an agreement based on self-determination which confers on Nagorno-Karabakh the highest degree of self-rule within Azerbaijan;
     - guaranteed security for Nagorno-Karabakh and its whole population, including mutual obligations to ensure compliance by all the Parties with the provisions of the settlement (Lisbon Document, 1996).

The General Secretariat of the OIC made statements on Armenia-Azerbaijan conflict supporting the position of Azerbaijan, subsequently the OIC conferences adopted weighty resolutions on Armenia-Azerbaijan conflict. In these resolutions (OIC Resolution No. 12/21-P, conflict between Armenia and Azerbaijan, OIC Resolution No. 10/30-C, On the Destruction and Desecration of Islamic Historical and Cultural Relics and Shrines in the Occupied Azeri Territories resulting from the Republic of Armenia's aggression against the Republic of Azerbaijan,) the Armenia-Azerbaijan conflict is defined unambiguously as aggression of Armenia against the Republic of Azerbaijan.
