L'AQUILA, July 10 (RIA Novosti) - Russia, the U.S., and France said on Friday they would submit a revised set of proposals on the disputed region of Nagorny Karabakh to Armenia and Azerbaijan.

"We urge the presidents of Armenia and Azerbaijan to resolve the few differences remaining between them and finalize their agreement," Russian President Dmitry Medvedev, U.S. President Barack Obama, and French President Nicolas Sarkozy said in a joint statement.

The three countries are co-chairs of the Minsk Group, which mediates the territorial dispute between Baku and Yerevan.

The presidents of Armenia and Azerbaijan are expected to meet in Russia on July 17.

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 de facto government.

A war between Azerbaijan and Armenia over the mountainous enclave in 1988-1994 left an estimated 35,000 people dead. Sporadic violence on the border has continued ever since.

Azerbaijani President Ilham Aliyev and Armenian President Serzh Sargsyan met in Prague last month to discuss the conflict, on the sidelines of the EU's Eastern Partnership summit, and said some progress had been reached.
