The US’s Federal Communications Commission is making a push to ban Chinese companies and technology from undersea internet cables connected to the US. 

On Wednesday, the FCC’s Chair Brendan Carr introduced the proposal, citing the need to protect the undersea fiber optic cables from potential spying threats, including foreign governments. 

“We have seen submarine cable infrastructure threatened in recent years by foreign adversaries, like China. We are therefore taking action here to guard our submarine cables against foreign adversary ownership, and access as well as cyber and physical threats,” Carr said in a statement. 

The proposal calls for automatically blocking “foreign adversary-controlled license applicants” from owning a stake in an undersea cable. It would also limit “capacity leasing agreements to such entities” while banning the use of certain equipment from being used in the undersea cables.

In addition, the proposal would establish new “cybersecurity and physical security requirements, and more—all while streamlining the Commission’s license review procedures,” the FCC said.  Whether the measures apply to existing or just new cables was left unclear.

Although Carr didn't cite any specific examples, there's been a growing number of incidents involving Chinese ships allegedly disrupting undersea cables, especially those to Taiwan.

Carr introduced the measure after the FCC voted in May to ban electronic vendors from hiring Chinese labs to test their products before receiving FCC clearance to import and sell them in the US.  The Commission also cited national security concerns, warning that foreign government-linked labs could exploit the certification process to slip insecure telecom gear into the US market for potential surveillance use.

“The FCC estimates that today, roughly 75% of all electronics are tested in labs located inside China,” Carr noted at the time. 

The Commission’s push to block Chinese tech from US-connected undersea cables could also be far reaching. If passed, the measure will also look at  “various additional measures to protect submarine cable security against foreign adversary equipment and services, while incentivizing the use of American submarine cable repair and maintenance ships and the use of trusted technology abroad,” the FCC said. 

The Commission is slated to vote on the undersea cable proposal during the Commission’s next meeting on August 7th. In a blog post, Carr also said the proposal follows President Trump’s “America First Investment Policy Memorandum.”

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
