Speaking in an interview broadcast today, Dmitry Medvedev said if Russia stopped selling arms, other suppliers would soon step in and this could destroy the balance of forces in the Caucasus region.
Both Azerbaijani and Armenian forces this month have used artillery, tanks and other weapons on a scale not seen since a separatist war ended in 1994.
The war left Karabakh, officially part of Azerbaijan, under the control of local ethnic Armenian forces and the Armenian military.
