China river oil spill ‘serious’
China’s Yellow River tributaries have been “seriously polluted” by an oil spill last week, further contaminating badly-tainted drinking water resources, state media has said. Last week a ruptured pipe operated by China’s oil giant, PetroChina, sent 150,000 litres of fuel down two major tributaries of the Yellow River, Chishui and Wei. China National Petroleum Corporation, the parent company and the country’s largest oil producer, said the leak was caused by a “third party” during construction work. The pipeline is supposed to transport diesel from northwest China’s Gansu province to central parts of the country.
