Azerbaijan's foreign minister said preparations were made for a meeting between Armenian President Robert Kocharian and his Azeri counterpart, Ilham Aliyev, on the dispute. That meeting is scheduled to be held later this week in Kazan.
Nagorno-Karabakh, a mostly ethnic Armenian enclave, broke away from Soviet Azerbaijan in 1988, sparking a war in which some 35,000 people were killed.
In 1994, Armenia and Azerbaijan agreed to a cease-fire, but they remain technically at war over the territory.
