China declared its "indisputable sovereignty" over the South China Sea and held naval drills in the waters, pushing back against a U.S. role in resolving disputes in one of the world's busiest shipping lanes.

"China has indisputable sovereignty of the South Sea and China has sufficient historical and legal backing" to underpin its claims, Geng Yansheng, a Ministry of Defense spokesman, told reporters at a military compound outside Beijing today. It opposes efforts to "internationalize" the issue and will resolve differences through "friendly negotiation," he said.

U.S. Secretary of State Hillary Clinton last week called the sovereignty issue "a leading diplomatic priority." Chinese Foreign Minister Yang Jiechi subsequently called her comments "virtually an attack on China" and said U.S. involvement "can only make matters worse and more difficult to solve."

The Chinese government considers the entire South China Sea as its own, dismissing claims from Southeast Asian countries to islands such as the Spratlys, and is building an ocean-going fleet to project power beyond its borders. China told Exxon Mobil Corp. and BP Plc to halt exploration in areas that Vietnam considers part of its territory, according to U.S. government agencies.

China's military recently held a large-scale naval exercise in the sea using "real weaponry," Geng said. The exercise, involving warships from three naval fleets, included missile launches at long-range targets and practicing against jet fighters, the state-run China Daily reported today.

David Fuller's view Was it Talleyrand who said in the 18th century: "Countries don't have friends; they have interests." There are many variations on this statement. I believe Charles deGaulle's translated version was: "Nations don't have friends or enemies…nations only have interests."

Whatever, China and its chequebook are the runaway winners in the global scramble for strategic resources and it is likely to be more assertive in the search for oil and gas closer to home.
