Russian state oil giant Rosneft is hoping tax concessions from Moscow will unleash billions of dollars in investment on a major new onshore development in the north of the Krasnoyarsk region in East Siberia.

The proposed Vostok Oil project, a joint venture between Rosneft and privately held Neftegazholding, is set to add a major, world-class oil province fo Russia, Rosneft deputy executive chairman Pavel Fyodorov said.
