The major disagreement between both sides at the Bucharest conference was the status of Artsakh. Azerbaijan's preferred solution would be to give Artsakh the "highest status of autonomy adopted in the world". Armenia, on the other hand, endorsed a popular vote by the inhabitants of Artsakh to decide their future, a position that was also taken by the international mediators. On 27 June, the Armenian foreign minister said both parties agreed to allow the residents of Artsakh to vote regarding the future status of the region. The Azerbaijani Ministry of Foreign Affairs officially refuted that statement. According to Azeri opposition leader Isa Gambar, however, Azerbaijan did indeed agree to the referendum. Still, nothing official has confirmed this yet.
