A month ago, the co-chairs of the Organization for Security and Co-operation in Europe (OSCE) Minsk Group said that the leaders of Armenia and Azerbaijan had confirmed their readiness to hold a high-level meeting before the end of 2015.
The last meeting between the two country's leaders took place in October 2014, also in the French capital.
The conflict between Armenia and Azerbaijan began in 1988, after the predominantly Armenian Nagorno-Karabakh autonomous region announced its secession from the Azerbaijan Soviet Socialist Republic. The territory proclaimed itself independent in 1991, prompting a war that lasted until a Russia-brokered ceasefire was signed in 1994. According to local media, tensions in the region remain high.
The OSCE Minsk Group, co-chaired by the United States, Russia and France, has been mediating the Nagorno-Karabakh conflict since 1992.
