HANOI, Vietnam, May 14 (UPI) -- China has no sovereignty over waters in the South China Sea where it has deployed government vessels alongside an oil rig, a Vietnamese historian said.
China National Offshore Oil Corp. deployed drilling rig HD-981 about 120 miles off the coast of Vietnam in disputed waters in early May. Both sides make competing claims over the territory, though the Chinese government has been accused of taking provocative action in response.
