MOSCOW, July 15 (RIA Novosti) - The presidents of Russia, Armenia, and Azerbaijan will discuss the Nagorny Karabakh peace process in Moscow on Saturday, a Russian presidential aide said on Wednesday.

"The meeting is due to take place on July 18 in the Kremlin," Sergei Prikhodko said.

He added however that there were "no plans to sign any documents" at this stage.

"The most important thing is to bring the sides' positions closer," he said.

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

The presidents of Azerbaijan and Armenia, Ilham Aliyev and Serzh Sargsyan, discussed the conflict in early May in Prague on the sidelines of the EU's Eastern Partnership summit.

A war between Azerbaijan and Armenia over the mountainous enclave in 1988-1994 left an estimated 35,000 people dead.
