“Cyber attacks from China are completely intolerable and cause serious harm to our national security and our economy," Senator Pat Toomey said in a statement. "These charges must be vigorously prosecuted and appropriate measures taken. If true, these are outrageous acts of economic espionage that threaten companies and jobs here in Pennsylvania.”

"For too long, China’s unfair trade practices and economic policies have cost jobs in Pennsylvania and across the U.S.," said Senator Bob Casey in a statement. "The U.S. trade deficit with China set a new record for the fourth straight year in 2013, reaching $318.4 billion. This move is further evidence of China’s anti-competitive trade practices, which have taken a dramatic toll on Pennsylvania businesses and pose a threat to our national security."
