Vietnam's claims do not hold water
In safeguarding its marine rights and interests, China attaches great importance to legitimacy. In dealing with the disputes in the South China Sea, China complies with the United Nations Convention on the Law of the Sea and international norms.
UNCLOS grants coastal states sovereignty over territorial seas and sovereign rights to explore and exploit the natural resources in exclusive economic zones. In 1996, China drew baselines for the Xisha Islands and measured the territorial sea and exclusive economic zones accordingly.
China abides by UNCLOS in exploring and exploiting natural gas and oil resources in the South China Sea, and Vietnam has no right to criticize China's drilling platform that has entered into operation near the Xisha Islands.
