Apparently, Indian Oil Corporation (IOC) and Petronet are jointly pursuing to buy LNG from Exxon Mobil so that "we do not approach the same seller separately, resulting in price rise," IOC’s director-planning and projects BM Bansal said.
The article also states that IOC may also be interested in buying 10% stake in the PNG venture once AGL Energy decides to exit the venture.
