Russia does not believe that peaceful settlement in Karabakh can depend on conducting constitutional referendum in the region.

“We do not recognize Nagorno-Karabakh as an independent state," TASS reported quoting Russian foreign ministry’s information and press department said. “We consider that its status should be determined through political talks in the framework of the Minsk process.”

Constitutional referendum in the Nagorno-Karabakh Republic is set for February 20. The reform envisages transition from semi-presidential to presidential form of government.
