Gazprom Neft has not yet made an offer to participate in the purchase nor received any proposals from Russia's Rosneft for a joint buy, Mr. Dyukov said.
"We are interested in this asset. We are evaluating it to participate in the sale. But we have not received any official offers from Rosneft and have not made such offers ourselves," Gazprom Neft head was quoted as saying.
Earlier reports said Gazprom Neft and Rosneft might buy Lotos jointly.
