Echoing concerns raised two months ago by eight Senate colleagues in a letter to officials of the Obama Administration, four Senate lawmakers are urging FCC Chairman Julius Genachowski to review the national security implications of equipment contracts between domestic U.S. wireless carriers and Chinese network equipment firms. In a letter delivered on Wednesday, Senators John Kyl (R-AZ), Joseph Lieberman (I-CT), Susan Collins (R-ME) and Sue Myrick (R-NC) warn specifically against a proposed equipment deal between Huawei Technologies—one of the world’s fastest growing suppliers of telecom network gear—and Sprint Nextel, which is currently considering Huawei’s offer as one of six Sprint has received for a multibillion-dollar network upgrade. A second Chinese equipment firm, ZTE Corp., is included among the six bidders for the Sprint contract, and observers say that Sprint is likely to announce its selection in about two weeks. As in the previous Senate letter, the four lawmakers cautioned Genachowski about Huawei’s ties with the Chinese government as they noted that Huawei’s current chairwoman had served as a captain in the Chinese People’s Liberation Army and had worked in China’s Ministry of State Security before joining the company in 1992. As such, the lawmakers argued that Huawei, ZTE and other Chinese network equipment firms are subject to “significant influence by the Chinese military.” While requesting details on the extent to which the FCC is empowered to review carrier purchases of foreign technologies, the four Senate members told Genachowski that “the sensitivity of information transmitted in communications systems, as well as the potential for foreign espionage, requires that the government take decisive action.” Although the FCC declined to comment, Huawei asserted in reply to the August letter that it is a private company in which “government or military organizations do not hold any shares, or control the company in any form.”
