According to him, the mediators are making efforts to resolve the conflict.
Nevertheless, the parties of the Nagorno-Karabakh conflict should have political will in order to achieve progress, the secretary general added.
Greminger noted that the purpose of his visit to Baku is to study potential for further development of relations between Azerbaijan and the OSCE.
Azerbaijan as an active OSCE member makes an important contribution to the activities of the institution, including the establishment of dialogue and political, military issues, Greminger said adding that, OSCE highly appreciates this and believes that there is potential for further development of cooperation.
The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. As a result of the ensuing war, in 1992 Armenian armed forces occupied 20 percent of Azerbaijan, including the Nagorno-Karabakh region and seven surrounding districts.
The 1994 ceasefire agreement was followed by peace negotiations. Armenia has not yet implemented four UN Security Council resolutions on withdrawal of its armed forces from the Nagorno-Karabakh and the surrounding districts.
