The sides discussed regional events and challenges, as well as the current state of negotiations on the Nagorno-Karabakh conflict.

The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. Armenian armed forces have occupied Nagorno-Karabakh and seven surrounding regions of Azerbaijan.
Azerbaijan and Armenia signed a ceasefire agreement in 1994. The co-chairs of the OSCE Minsk Group - Russia, France and the U.S. are currently holding peace negotiations.
Armenia has not yet implemented the U.N. Security Council's four resolutions on the liberation of the occupied territories.
