BP's difficulties in the deal with Rosneft. In mid-January 2011 BP signed a deal with Rosneft with each company investing in the other through a stock swap of 5% of BP and 9.8% of Rosneft.

Robert Dudley, who headed the Russian operations of BP, is now CEO of the company. From 2003 to 2008, Dudley headed the TNK-BP joint venture. BP's partners in that venture, known as the AAR group of oligarchs, have sued BP over the BP-Rosneft deal. An arbitration tribunal in Sweden ruled that the Rosneft venture violates a shareholder agreement BP has in the TNK-BP venture.

Russian President Medvedev has asked political leaders to give up corporate positions, which would mean Sechin would have to give up his position in Rosneft. BP continues to benefit from access to new resources in Russia even with these difficulties. BP contributed $6 billon in cash in 2003 to the TNK-BP joint venture. BP has made $14.3 billion in dividends since 2003 on this investment and holds 50% of the assets in that venture. ...
