US proposes restricting Chinese optical modules in AI infrastructure; Beijing condemns 'bullying' tech curbs as Xi-Trump summit approaches

Summary

The US Federal Communications Commission is planning restrictions on next-generation Chinese optical modules used in AI and data-centre networks, preserving existing supplies while barring new-generation products, the South China Morning Post reported. Beijing's state press called the move "bullying," warning that US bans on Chinese green energy and advanced manufacturing would damage American industry as much as Chinese firms; Beijing also defended its open-source AI models. The measures are the latest round in a broadening US-China tech dispute that now covers AI hardware, robotics, drone exports, and advanced manufacturing. Analysts cited by SCMP described the FCC plan as "mild," noting Washington is balancing security concerns against the cost of replacing Chinese supply capacity. The escalation comes as AI, robotics, and forced-labour claims are all mounting as friction points ahead of a planned summit between US President Donald Trump and Chinese President Xi Jinping in Washington in September.

The split

Coverage comes exclusively from South China Morning Post, the Hong Kong-based daily that occupies a space between mainland Chinese and Western framing; no Chinese-language mainland coverage or Western-wire reporting was in the feed. SCMP's analysis emphasised that analysts view the FCC plan as "mild," tempering the signal from Beijing's sharp "bullying" rhetoric. What is missing: US-government or Congressional framing of the FCC plan's rationale; independent European or Southeast Asian perspectives on how the measures land for third-country AI supply chains.

By the numbers

• 3, months until Xi Jinping's planned Washington visit (September 2026)
• Next-generation, the targeted scope of the FCC optical-module restriction (existing supplies preserved)
• 6, US entities blacklisted by Beijing in the same round of countermeasures
• 59, countries affected by recent fresh US tariffs that Beijing cited as the trigger for its retaliation

Why it matters

Chinese optical modules are central to the high-speed interconnects inside large-scale AI clusters; an FCC ban on next-generation components would force US data-centre operators to find alternative suppliers, raising costs and potentially slowing AI infrastructure expansion. The restriction represents Washington extending its chip-and-tool controls into the network-hardware layer that underpins AI at scale. Beijing's framing of the measures as "bullying" signals that further retaliation is on the table, even as the FCC plan is being described as relatively contained.

What to watch

• Whether the FCC plan advances to a formal rule-making or remains a proposal
• How data-centre operators respond to potential supply-chain shifts on optical interconnects
• Whether the Xi-Trump September summit produces any agreed carve-outs or trade-framework commitments on AI hardware
• China's next retaliatory step, given Beijing's explicit warning that "further actions" remain available
