New information about Chinese civilian telecommunications companies’ close support of the Chinese military and information warfare programs is raising fresh concerns about the companies’ access to U.S. markets, according to a congressional report. One of the companies identified in the report as linked to the People’s Liberation Army (PLA) is Huawei Technologies, a global network hardware manufacturer that has twice been blocked by the U.S. government since 2008 from trying to buy into U.S. telecommunications firms.
