Speaking to the UN General Assembly, Foreign Minister Elmar Mammadyarov said international law and four relevant Security Council resolutions should form the legal basis of a resolution of the conflict.
Mammadyarov rejected the statement from his Armenian counterpart, Vartan Oskanian, who told the General Assembly that a Karabakh solution should be negotiated only through the OSCE, the Organization for Security and Cooperation in Europe.
Nagorno-Karabakh is an enclave inside Azerbaijan with a mostly ethnic Armenian population. Armenian forces seized control of Nagorno-Karabakh from Azerbaijan in a war in the early 1990s that claimed an estimated 30,000 lives.
A cease-fire was signed in 1994, but the two countries have failed to negotiate a settlement on the region's status.
