MOSCOW REGION, November 2 (RIA Novosti) - The leaders of Russia, Armenia and Azerbaijan agreed on Sunday to work together for improving the situation in the Caucasus and instructed their foreign ministers to intensify efforts to settle the Nagorny Karabakh conflict.

Azerbaijani President Ilham Aliyev and Armenian President Serzh Sargsyan met in the presence of Russian President Dmitry Medvedev to discuss a settlement to the conflict. Following the meeting, the three presidents signed a declaration on the Nagorny Karabakh dispute.

The declaration calls for a peaceful settlement of the conflict on the basis of international law and decisions and documents adopted within this framework to create favorable conditions for economic development and comprehensive cooperation in the region.

Nagorny Karabakh, a region in Azerbaijan with a largely Armenian population, declared its independence from Azerbaijan to join Armenia in 1988 and has been a source of conflict ever since.
