Russia can increase its oil production to as much as 700 million tonnes of oil per year (14 million barrels of oil per day) and export 300 billion cubic meters of gas to China annually, Rosneft Chief Executive Igor Sechin said on Friday.

A weak ruble is offsetting low oil prices for Russian oil producers. (Reporting by Katya Golubkova; Editing by Richard Pullin )
