MOSCOW: Russia's largest oil producer Rosneft will buy around 6 million tonnes of oil worth over $2 billion from domestic producers next year, according to an announcement on a state-owned website for purchases of companies' needs.

According to the website, Rosneft will buy 5.14 million tonnes of oil worth 132.5 billion roubles ($1.9 billion) from Gazprom Neft.

The price works out at around $46 per barrel compared to a current price of Russian Urals crude blend of $51 per barrel.
