Head of the Inter-Ethnic Relations Section of Russian Institute for Political and Military Analysis Sergey Markedonov believes that the Kremlin does not show interest towards developing relations with the Nagorno Karabakh. «September 2 past year some 40 US Congressmen congratulated the NK authorities on the NKR Independence Day, but no single Russian legislator did it. Russian business is almost absent in Karabakh, which is the most advanced in the economic respect out of the unrecognized republics,» he said. «Unrecognized republics have their political, social institutions, military structures, internal legitimacy, national and historical myth. In most cases they cannot sustain their existence without Russia's support,» Sergey Markedonov believes. In his opinion, actual reality demands new approaches from Moscow towards frozen conflicts, reported RFE/RL.
