Russian state-owned oil company Rosneft has bought the newly-made company Baikal Finance Group which bought Yukos' key production unit Yuganskneftegaz.
According to Interfax news agency, Rosneft bought 100 percent of the shares in Baikal for an undisclosed sum.
Under the purchase, Rosneft gets more than three-quarters of the shares in Yukos' Yuganskneftegaz production unit.
"The owners of Baikal Finance Group made us an offer to sell their company, and we took it," Alexander Stepanenko, spokesman for Rosneft said.
State-run Rosneft's purchase of Baikal would seem to confirm the predictions of analysts who said that Yuganskneftegas would fall into government-controlled hands.
