Keith,

"I would expect further declines out of China as it begins to shut down business to help the air pollution problem in Beijing for the Summer Olympics.

As a reminder China has indicated that from July 27-Sept 20th they will require Beijing and the 5 provinces surrounding it (Hebei, Inner Mongolia, Shanxi, Shandon and Tianjin) to comply with Beijing's air standards.

Furthermore it is estimated that Beijing will need 300m cubic meters of water to flush polluted and stagnated rivers, canals and lakes in central Beijing for the games -(
