Vladimir Karapetyan said the OSCE Minsk Group co-chairmen are expected to meet with Armenian President Robert Kocharyan and Foreign Minister Vardan Oskanyan, adding that it was currently unclear whether the mediators would visit Stepanakert, the capital of Azerbaijan's breakaway republic of Nagorno-Karabakh.
After their visit to Armenia, the OSCE Minsk Group co-chairman will travel to Azerbaijan to meet with the country's leaders.
The Organization for Security and Cooperation in Europe (OSCE) Minsk Group was created in 1992 to encourage a peaceful resolution to the conflict between Azerbaijan and Armenia over Nagorno-Karabakh. The group is co-chaired by U.S., Russian and French representatives.
The conflict between the two former Soviet republics over Nagorno-Karabakh, a region in Azerbaijan with a largely Armenian population, first erupted in 1988 when it declared independence from Azerbaijan to join Armenia.
Over 30,000 people were killed on both sides between 1988 and 1994, and over 100 died following a 1994 ceasefire. Nagorno-Karabakh remained in Armenian hands, but tensions between Azerbaijan and Armenia have persisted.
