OREANDA-NEWS. June 15, 2007. Rosneft offered to buy Yukos's assets in southern Russia for 4.9 billion rubles or $190 million after regulators blocked the company of a May auction from acquiring them.

Rosneft made the offer for Yukos's stakes in regional power utilities and an oil and gas exploration unit on June 9 and is waiting for an answer.

Rosneft has become the country's largest oil producer and refiner after buying Yukos assets at forced auctions this year.
