Chinese oil rig is moving towards Hainan island - Vietnam coastguard
Admiral Ngo Ngoc Thu, chief of staff of the Vietnam coast guard told Reuters by telephone the rig was about 30 nautical miles from Triton island in the Paracels and had been moving towards Hainan since late on Tuesday night.
Thu did not give any reason why the rig had moved and said Vietnam's boats were still watching the area closely.
China's official Xinhua news agency reported earlier on Wednesday that the rig had finished exploration work two months after its deployment to waters claimed by China and Vietnam.
