Google Gets U.S. Backing and Evidence China May Be Behind the Attack

The U.S. said Friday it will file a formal complaint against China next week, as new details emerged about the cyber-attack that prompted Google (GOOG) to threaten to quit the world's largest country. The White House offered its support for Google's position, and the State Department said it would demand an explanation from China about the attack that targeted U.S. companies and Chinese human rights workers. And U.S. lawmakers are urging high-tech companies to join Google in reassessing their business operations in China.
