China has reported a fresh oil spill in the Bohai Bay off its northeastern coast, following two spills last month, AP reported. The State Oceanic Administration reported Tuesday that spill was caused by a malfunction in the centralized control system for the Suizhong 36-1 oilfield's central platform, operated by China National Offshore Oil Corp. It said CNOOC used oil absorbent mats and sprayed oil dispersant to clean up the 1 square kilometer (0.4 sq. mile) spill. Following the earlier spills, also in the Bohai Bay, the government ordered CNOOC and other offshore oil companies to do more to minimize risks of such accidents.
