Vietnam demanded China stop oil drilling operations in a
disputed patch of the South China Sea, saying on Monday that Beijing's
decision to deploy a deep sea rig over the weekend was illegal.
China dismissed the objections, saying the activity was being carried out in its territorial waters.
Beijing's
increasingly assertive territorial claims to the waters, which are
thought to have large oil and gas deposits beneath them, have angered
Vietnam, the Philippines and other claimants. The region is widely seen
as a potential area of conflict.
Last week, President Barack Obama
signed a new defense pact with the Philippines aimed at reassuring
Asian allies of American backing as they wrangle with Beijing's growing
economic and military might.
The China Maritime Safety
Administration posted a navigational warning on its website advising
that the CNOOC 981 rig would be drilling in the South China Sea from May
4 to Aug. 15, in an area close to the Paracel Islands, which are
controlled by China but Vietnam claims as its own.
China's maritime administration also said that ships entering a 3-mile (4.8-kilometers) radius around the area are prohibited.
Vietnam's
foreign ministry said the area where the rig was stationed lay within
Vietnam's exclusive economic zone and continental shelf as defined by
the 1982 U.N. Convention on the Law of the Sea.
"All foreign
activities in Vietnam's seas without Vietnam's permission are illegal
and invalid," the ministry said in a statement. "Vietnam resolutely
protests them."
Vietnam's state-owned oil company, PetroVietnam,
demanded that China National Offshore Oil Corporation "immediately stop
all the illegal activities and withdraw the rig from Vietnamese waters."
Asked
about Vietnam's objections, Chinese Foreign Ministry spokeswoman Hua
Chunying said the drilling was taking place in Chinese waters.
Many
analysts believe China is embarking on a strategy of gradually pressing
its claims in the water by seeing what it can get away with, believing
that its much smaller neighbors will be unable or unwilling to stop
them. Vietnam has accused Chinese ships of cutting cables to its
exploration vessels and harassing fishermen, as has the Philippines.
Chinese
assertiveness puts Vietnam's authoritarian government in difficult
position domestically because anger at China, an ideological ally, runs
deep in the country. This is exploited by dissident movements, who
accuse the government of being unwilling to speak out against Beijing.
Tran
Cong Truc, the former head of a government committee overseeing the
country's border issues, said the latest Chinese move was especially
provocative.
"This act by China is much more dangerous than previous actions such as cutting the exploration cable or fishing bans," he said.
