US Lawmakers Demand Chinese Telecoms Detail Ties to Military and Government

/in /tarafından

The leaders of a U.S. House of Representatives panel have urged top Chinese telecom companies to provide detailed information about any connections to the Chinese military and government, citing national security concerns over their operations in the U.S. Representatives Raja Krishnamoorthi, the top Democrat on the House Select Committee on China, and Republican John Moolenaar, the committee chair, have sent letters to China Mobile, China Telecom, and China Unicom, requesting responses by March 31.

The lawmakers expressed concerns that the companies could misuse their access to U.S. data through cloud and internet services, potentially sharing sensitive information with the Chinese government. This follows a 2024 Reuters report revealing a U.S. Commerce Department investigation into these companies’ operations in the U.S. and the potential security risks they pose.

In one letter, the committee raised alarms about China Telecom’s operations, particularly its role in internet backbone exchanges and cloud computing. The lawmakers warned that such operations could facilitate unauthorized data access, espionage, or sabotage by the Chinese government. They also highlighted the companies’ documented connections to Chinese intelligence, intensifying national security concerns amid China’s increasing cyber-attacks on U.S. telecommunications infrastructure.

The letters reflect growing bipartisan concern over Chinese telecom firms’ U.S. presence, especially after significant cyber-attacks tied to Chinese state-backed groups. Two prominent cyber incidents—Salt Typhoon and Volt Typhoon—have been linked to Chinese government entities, with the latter described by the FBI as the largest cyber-espionage campaign in U.S. history. Beijing has denied any involvement in these attacks.

China Telecom, China Mobile, and China Unicom have long been under scrutiny in Washington. The Federal Communications Commission (FCC) denied China Mobile’s application to offer U.S. telecom services in 2019 and revoked China Telecom and China Unicom’s authorizations in 2021 and 2022. In 2024, the FCC moved to bar these companies from offering broadband services, but the decision was blocked by a court. Despite these regulatory actions, the companies still retain the ability to provide cloud services and handle U.S. internet traffic, thus maintaining access to Americans’ data.

U.S. Lawmakers Call for Scrutiny of Baicells, Chinese Telecom Firm

Baicells, a Chinese telecom hardware manufacturer founded by former Huawei employees, is facing heightened scrutiny from U.S. lawmakers over national security concerns. John Moolenaar, the top Republican on the House Select Committee on China, emphasized the need for rigorous government oversight of Baicells, citing potential cyber vulnerabilities in the company’s products. He warned that any presence of such companies in U.S. networks, particularly in sensitive areas, should raise significant national security alarms.

Despite Baicells’ reassurances that its products do not pose security risks, the company is under investigation by the FBI and the U.S. Department of Commerce. The company has provided base stations and routers to more than 700 U.S. networks, including those near military installations. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has flagged Baicells’ firmware for cyber vulnerabilities, further raising concerns.

Baicells’ chairman, Sun Lixin, defended the company by stating that all tech companies, regardless of their size, continuously release updates to address security vulnerabilities. He also expressed willingness to cooperate with U.S. inquiries.

The scrutiny of Baicells is part of a broader concern in Washington over the potential for Chinese-linked companies to compromise U.S. telecommunications networks. U.S. officials have warned that China-linked suppliers, including state-backed hacking groups like “Volt Typhoon,” could exploit network vulnerabilities for espionage.

Democratic leaders in Congress, including Frank Pallone and Mark Warner, have called for greater accountability and quicker responses to national security risks posed by foreign adversaries in U.S. telecom networks. They argue that focusing on individual companies without addressing systemic risks is insufficient to protect critical infrastructure.

 

US Responds to Chinese-Linked Cyber Attacks on Telecoms Firms

The United States has taken action in response to Chinese-linked cyber-espionage operations targeting U.S. telecom firms, as confirmed by U.S. national security adviser Jake Sullivan on Friday. Telecom giants AT&T and Verizon disclosed late last year that their networks had been breached by cyber attackers, although both companies have since secured their systems after collaborating with the U.S. government and law enforcement agencies.

Sullivan highlighted the U.S. government’s efforts to address the ongoing threat, mentioning specific cyber operations like “Salt Typhoon” and “Volt Typhoon.” He emphasized that the U.S. has conveyed a clear message to the People’s Republic of China (PRC) regarding the consequences of further actions that could jeopardize American critical infrastructure, underscoring that the U.S. is prepared to respond accordingly.
