In this Tuesday, July 20, 2010 photo, the surface of a beach is covered by the spilled crude oil in Dalian, a coastal city in northeast China's Liaoning province. The oil had spread over water since a pipeline at the busy northeastern port exploded, hurting oil shipments from part of China's strategic oil reserves to the rest of the country.
