Chinese cyber-spying seen growing against US

China's government appears increasingly to be piercing US government and defense industry computer networks to gather useful data for its military, a congressional advisory panel said on Thursday. "A large body of both circumstantial and forensic evidence strongly indicates Chinese state involvement in such activities," the U.S.-China Economic and Security Review Commission said in its 2009 report to Congress. The 12-member, bipartisan commission was set up in 2000 to analyze the implications of growing trade with China. Beijing has begun to broaden its national security concerns beyond a potential clash across the Taiwan Strait and issues around its periphery, the 367-page report said. China is the most aggressive country conducting espionage against the United States, focused on obtaining data and know-how to help military modernization and economic development, it added.
