The U.S. House of Representatives' Committee on Intelligence held an open hearing in Washington, D.C. to question Huawei and ZTE about possible threats they pose to national security.
Committee Chairman Mike Rogers said he called the hearing because "Huawei and ZTE provide a wealth of opportunities for Chinese intelligence agencies to insert malicious hardware or software implants into critical telecommunications components and systems. And under Chinese law, ZTE and Huawei would likely be required to cooperate with any request by the Chinese government to use their systems or access for malicious purposes."
Charles Ding, Corporate Senior Vice President, Huawei, said that cyber security is a global issue for the the whole industry and denied any involvement from the Chinese government in Huawei's products or operations.
Zhu Jinyun, ZTE’s Senior Vice President for North America and Europe, also testified that China's government has never made a request to access ZTE's telecom infrastructure equipment for a cyber attack, and that the operations of ZTE USA are bound by U.S. law.
