From the Financial Times:
"Some of the world’s biggest energy companies, including ExxonMobil and Gazprom, have been thrust into the deteriorating territorial dispute between China and Vietnam in the resource-rich South China Sea.
Vietnam on Wednesday accused China of acting “illegally” after state-owned China National Offshore Oil Corporation (Cnooc) invited foreign companies to tender for exploration rights in an area that Hanoi says infringes on blocks that it has already licensed to America’s ExxonMobil and Russia’s Gazprom."
