Details behind China oil spill emerge

THE first details have emerged on the cause of China’s largest reported oil spill as environmentalists urged the government to do more to warn locals of potential dangers.

The oil spill has spread over at least 165 sq miles of water after a pipeline at the busy north-eastern port of Dalian exploded a week ago.

The disaster has caused China to take a hard look at its ports, some of the busiest in the world.
