Kabulov responded negatively to the question if Moscow sees the risk that New Delhi, under US pressure, could refuse to buy Russian oil.
"No ... they [New Delhi] will not be engaged in this," the diplomat said.
He said India wants to buy a lot of oil because it is profitable for India.
"India and China have, for obvious reasons, a good discount," Kabulov said.
Earlier, Russian President Vladimir Putin and Indian Prime Minister Narendra Modi have discussed in detail the prospects for practical cooperation in the energy field and other areas during a phone conversation.
