China Unicom warns US crackdown on Chinese telecoms could disrupt global networks

The Chinese telecom giant told the FCC that banning interconnections with Chinese carriers would fracture US-China communications and boomerang on American companies operating abroad.

China Unicom’s US subsidiary filed comments with the Federal Communications Commission on June 9, warning that a proposed Trump administration rule banning American telecom companies from interconnecting with Chinese firms would blow a hole in global communications infrastructure.

What the proposed rule would actually do

The FCC’s proposed regulation would prohibit American telecommunications carriers from maintaining interconnection agreements with Chinese firms on the agency’s national security “Covered List.” That list includes the three biggest names in Chinese telecom: China Unicom, China Mobile, and China Telecom.

When you make a call, send a message, or transmit data between the US and China, that traffic has to physically travel through infrastructure operated by carriers on both sides. Those carriers have agreements with each other to hand off that traffic seamlessly. The FCC wants to sever those handshake deals entirely.

China Unicom argued in its filing that barring these interconnections would disrupt critical communication links between the two countries. American companies with extensive business operations in China, the company warned, would face direct harm. Supply chains across multiple industries could be affected.

A crackdown years in the making

The FCC has been tightening restrictions on Chinese telecom operators on US soil since 2019, when it denied China Mobile’s application to provide telecom services in the country. The rationale then, as now, was national security, specifically fears that Chinese state-linked carriers could be used for espionage or data interception.

The agency revoked China Unicom Americas’ US operating authority in 2022, stripping the company of its ability to provide domestic telecom services. The current proposal goes further by targeting the interconnection layer itself rather than just the license to operate within US borders.

Actions in April and May 2026 sought to bar the three Chinese operators from US data centers, adding another dimension to the regulatory squeeze.

What this means for investors

US corporations that rely on Chinese telecom services for cross-border data transmission would need to find alternative routing. For US carriers specifically, the rule would limit their options for routing traffic to and from China. Fewer routing options means less competition among transit providers. Any company running supply chain operations, cloud services, or real-time communications between the US and China should be paying close attention.

Companies that have built business models around seamless US-China connectivity may need to fundamentally rethink their architecture.

China Unicom’s warning about harm to US companies in China isn’t subtle. Beijing has demonstrated willingness to impose reciprocal restrictions on American firms operating on its soil, and US companies with significant Chinese operations would be caught in any tit-for-tat regulatory escalation.
