BP's spokesman dismissed the suggestions that the company was seeking to delay the process, saying that arbitration is still planned for March 7.
Earlier on Friday, the board of TNK-BP, Russia's third-largest oil company, failed to convene a meeting to review the partnership between BP and Russia's top oil producer, Rosneft
AAR had won an injunction to put the BP-Rosneft deal on hold at least until March 7.
The failure of the BP-nominated directors to show up for the TNK-BP board meeting... is disappointing, said the source close to one of the Russia-connected shareholders in the AAR consortium.
Having insisted that the arbitration should be accelerated, BP's actions now suggest they are seeking to delay, even sabotage the arbitration process, he said.
