MOSCOW, October 11 (RIA Novosti) - The Russian and Armenian presidents will discuss trade and military cooperation, prospects of energy projects and interaction in regional organizations in Moscow on Monday, a Kremlin source said Sunday.

Serzh Sargsyan will visit the Russian capital on an invitation from Dmitry Medvedev on October 12.

"Regular confidential political dialogue at the highest level gives dynamics to the Russian-Armenian partnership," the Kremlin source said, adding that despite the global financial crisis, Russia retains the positions of Armenia's leading foreign economic partner.

In January-August this year bilateral trade totaled $428.2 million - a 20.2% drop against the same period in 2008, but successful implementation of joint priority investment projects continues.

Medvedev and Sargsyan met Friday during a summit of the post-Soviet Commonwealth of Independent States in the capital of Moldova, with Azerbaijani President Ilham Aliyev also taking part in the meeting chiefly dedicated to discussions of the Nagorny Karabakh issue.

Nagorny Karabakh, a region in Azerbaijan with a largely Armenian population, has been a source of conflict between the former Soviet republics since the late 1980s. The province has its own government and is de facto independent.
