China's cyber abilities worry US

China's growing capabilities in cyber-warfare and intelligence gathering are a "formidable concern" to the United States, Director of National Intelligence James Clapper told the Senate Armed Services Committee: "The Chinese have made a substantial investment in this area, they have a very large organization devoted to it and they're pretty aggressive." "This is just another way in which they glean information about us and collect on us for technology purposes, so it's a very formidable concern," he said. Clapper, addressing questions at an annual hearing on worldwide security threats, did not elaborate on Chinese cyber activities. But in his written testimony, the intelligence chief said 2010 saw a "dramatic increase in malicious cyber-activity targeting U.S. computers and networks." The passage did not specifically mention China.
