The EU should engage more actively in solving the current conflicts in the South Caucasus, Chairman of European Institute for Caucasus and Caspian Studies in Berlin Matthias Dornfeld said.

There could be high ranking negotiations in Brussels with the active engagement of EC Vice-President Federica Mogherini, he said.

Furthermore, the German OSCE chairmanship should be more involved in the Nagorno-Karabakh conflict resolution, the expert said, adding that this could include track two diplomacy (non-governmental, informal and unofficial contacts and activities between private citizens or groups of individuals) as well as high ranking meetings in Berlin under the auspices of the Federal Government of Germany.

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.
