On 2 May 2014, a Chinese company’s HYSY 981 drilling rig started its drilling operation inside the contiguous zone of China’s Xisha Islands (see Annex 1/5 for the locations of operation) for the purpose of oil and gas exploration. With the first phase of the operation completed, the second phase began on 27 May. The two locations of operation are 17 nautical miles from both the Zhongjian Island of China’s Xisha Islands and the baseline of the territorial waters of Xisha Islands, yet approximately 133 to 156 nautical miles away from the coast of the Vietnamese mainland.
The Chinese company has been conducting explorations in the related waters for the past 10 years, including seismic operations and well site surveys. The drilling operation carried out by HYSY 981 this time is a continuation of the routine process of explorations, and falls well within China’s sovereignty and jurisdiction.
