China recently launched an oil and natural gas drilling platform that may be as significant as military modernization in buttressing Beijing's claims to control most of the islands, water and seabed in the maritime heart of Southeast Asia.

Designed to withstand typhoons, the giant rig was delivered to the state-owned China National Offshore Oil Corp. (CNOOC), the country's largest offshore energy producer. The company says it plans to use the platform to start drilling in the South China Sea in July.

It has not said where, but China's Global Times said that the deepwater rig, which is taken to its destination by powerful tugs, would "help China establish a more important presence in the largely untapped southern part of the South China Sea."
