The remarks by Russia came amidst a ranging controversy over alleged kickbacks and role of middlemen in the Rs 3,600 crore VVIP helicopter deal with an Italian firm Finmeccanica.
"In such important fields, that is technical and military cooperation, no mediators (should be there) because any mediator provides extra potential for corruption," Valentina Matvienko, chairperson of the Federation Council, Russian parliament's upper house, said here.
Maintaining that India-Russia defence deals are clean, Russia's highest-ranking female politician said, "During the last 10 years, luckily, we did not see any case of corruption".
"All this cooperation is based on inter-governmental agreements. So no mediators here can be present. It is performed directly through governmental structures that are empowered to do so in the field of military and technical cooperation," she said.
"So that is why it should be done directly on the level of two countries," Matvienko, who is a close ally of Russian President Vladmir Putin, said.
