Armenian Foreign Minister Edvard Nalbanyan said on Monday that Armenian and Azerbaijani presidents were likely to come together to negotiate the disputed territory of Nagorno-Karabakh by the end of 2013. A conflict between Azerbaijan and Armenia broke out in 1991 over the disputed territory of Nagorno-Karabakh when Armenia made territorial claims against Azerbaijan. Negotiations have so far failed to produce a permanent peace agreement. Nalbandyan said Armenia supported the Organization for Security and Co-operation in Europe (OSCE) Minsk Group, which encourages peace negotiations to the conflict between Azerbaijan and Armenia over Nagorno-Karabakh, and would keep supporting it. Referring to the OSCE co-chairs of the Minsk Group meeting in Vienna on July 13, Nalbadyan said " We have set a date for peace talks in this meeting. A summit may be held and Azerbaijani and Armenian presidents may come together by the end of 2013."
