WASHINGTON – A bipartisan group of eight US senators on Oct 21 urged US President Joe Biden to order a review of the security of the global network of undersea communications cables that handle nearly all the world’s internet traffic.

Nearly all international internet traffic travels on undersea cables and the locations of the cables are often openly published to prevent accidental damage.

“It is imperative that the United States undertake a review of existing vulnerabilities to global undersea cable infrastructure, including the threat of sabotage by Russia as well as the growing role of the People’s Republic of China in cable laying and repair,” said a letter on the issue from a group led by Republican Todd Young and Democrat Chris Murphy.

The US for years has expressed concerns about China’s role in handling network traffic and potential for espionage.

More than 400 subsea cables form the backbone of the internet, carrying more than 95 per cent of the world’s data traffic.

In 2020, US Federal Communications Commissioner Geoffrey Starks said the agency “must ensure that adversary countries and other hostile actors can’t tamper with, block, or intercept the communications they carry”.

The senators, including Mr Marco Rubio, Mr Brian Schatz, Mr Tim Kaine and Mr Dan Sullivan, said ensuring internet traffic security must be a national priority and raised a number of questions including what is the “administration’s overall strategy to guarantee the security of America’s undersea infrastructure and to promote the security of that of our allies and partners”?

They also asked what is the ideal size of the US-flagged and US-operated cable-laying and repair vessel fleet to ensure sufficient cable repair capacity, and how is the White House working to encourage other nations to choose trusted undersea cable manufacturers.

Reuters reported in 2023 that the US State Department and its partners had helped to prevent China from obtaining new subsea contracts in foreign places of US strategic interest, while other US agencies had prevented any cable from directly connecting US territory with China or Hong Kong over Chinese espionage concerns.

Since 2020, US regulators have been instrumental in the cancellation of four cables whose backers had wanted to link the US with Hong Kong.

In April, the US Federal Communications Commission (FCC) ordered the US units of China Telecom, China Unicom and China Mobile to discontinue broadband internet operations in the US. In June, the FCC advanced a proposal to boost the security of information transmitted across the internet after US government agencies said a Chinese carrier misrouted traffic.
