"Russia is one of the five permanent members of the Security Council, it is a very important member in the United Nations universe. It's a very active member, and in my areas of responsibility - an extremely positive interlocutor," Moller said.
Speaking of Russia's role in the Economic Commission for Europe, he said "Russia, of course, has a particularly important role to play. We always had extremely constructive discussions and very pragmatic approach to problems that we can always find a solution to."
"It [Russia] is one the very important countries in practically everything that we do," Moller added.
The UN Geneva office head noted, that the Ukrainian crisis did not seriously impact the partnership of the UN Geneva office with Russia.
"This is not New York, this is not the political part of the UN. This is the operational hub of the international system, where we are pragmatists, where we are dealing with day-to-day problems that affect everybody."
The United Nations failed to recognize Russia’s unification with Crimea, while United States and the European Union continue blaming Moscow of meddling in Ukraine’s inner affairs. Russia denies these accusations. Since March the West introduced several waves of anti-Russian economic sanctions, which have also impacted UN-Russia cooperation.
