Leaders of the U.S. Senate Intelligence Committee said on Tuesday they were concerned about what they described as China's efforts to gain access to sensitive U.S. technologies and intellectual property through Chinese companies with government ties. From a report: Senator Richard Burr, the committee's Republican chairman, cited concerns about the spread of foreign technologies in the United States, which he called "counterintelligence and information security risks that come prepackaged with the goods and services of certain overseas vendors. The focus of my concern today is China, and specifically Chinese telecoms (companies) like Huawei and ZTE that are widely understood to have extraordinary ties to the Chinese government," Burr said. Senator Mark Warner, the committee's Democratic vice chairman, said he had similar concerns. "I'm worried about the close relationship between the Chinese government and Chinese technology firms, particularly in the area of commercialization of our surveillance technology and efforts to shape telecommunications equipment markets," Warner said.
