China and Vietnam Clash in South China Sea

The Philippines coast guard detained Chinese fishing boats as well.

Strains between China and its neighbors burst to the surface in two parts of the South China Sea, taking the high-stakes struggle for control over the waters to new levels of friction.

Off Vietnam, dozens of Chinese military and civilian ships clashed with the Vietnamese coast guard, with Vietnamese officials complaining its vessels were repeatedly rammed. On the same day, Philippine police apprehended Chinese fishing vessels loaded with hundreds of sea turtles in disputed waters.

About 80 Chinese vessels moved into an area near the disputed Paracel Islands, where Hanoi has sought to prevent China from deploying a massive oil rig, said Rear Adm. Ngo Ngoc Thu, vice commander of the Vietnamese coast guard. He said the flotilla included seven military ships and that it was supported by aircraft.

He said the situation, which started brewing over the weekend, was "very tense" and said six Vietnamese officers had been injured in the standoff.

The confrontation—by far the most serious in recent years between the two neighbors—marked a significant escalation in Beijing's willingness to press its natural-resource claims, analysts said.

Theresa Fallon, a senior associate at the European Institute for Asian Studies, a Brussels-based think tank, said China's move represented the regional energy sector's "worst nightmare" and was bound to provoke Vietnam's anger.

"This is a huge rig—it's the size of a couple of football fields," Ms. Fallon said.

A senior administration official said the White House views the latest escalation as part of a pattern of behavior as China continues to try to advance its territorial claims. "We're obviously very concerned about it," the official said. "We have conveyed our concerns to the Chinese."

The standoff is "an unprecedented situation," said Ian Storey, a senior fellow at the Institute of Southeast Asian Studies in Singapore. The sheer number of Chinese vessels that appeared to be involved was a clear indication of China's "resolve to make sure this rig can operate in these waters."

China's state councilor described the move as part of Chinese business's normal operations and asked Vietnam to stop interfering, a Foreign Ministry spokesman said at a daily briefing.

China's Defense Ministry didn't respond to a request to comment.

Well, if Japan gets involved I wouldn't expect the Obama administration to lift a finger. They haven't been too forthcoming in the Ukraine situation, that's for sure.
