Bipartisan Senate Bill Would Sanction Foreign Saboteurs Targeting Undersea Internet Cables

A bipartisan Senate bill from Sens. Jeanne Shaheen (D-N.H.) and John Barrasso (R-Wyo.) would require sanctions on foreign individuals who sabotage undersea fiber-optic cables and increase U.S. resources for their protection and repair. The measure also calls for a 180-day report to Congress on alleged Chinese and Russian efforts to target these networks. Lawmakers cited recent cable cuts in the Baltic Sea and the Taiwan Strait as evidence of growing threats to global communications infrastructure.

Bipartisan Senate Bill Would Sanction Foreign Saboteurs Targeting Undersea Internet Cables

A bipartisan Senate proposal would require the United States to impose sanctions on foreign individuals who sabotage undersea fiber-optic cables that carry the bulk of global internet and communications traffic. The measure, introduced by Sens. Jeanne Shaheen (D-N.H.) and John Barrasso (R-Wyo.), also directs the federal government to devote additional resources and expand cooperation with allies and international organizations to secure and repair subsea cables.

The bill would mandate a report to Congress within 180 days documenting alleged efforts by China and Russia to target or undermine these networks. Lawmakers point to recent incidents — including cable cuts in the Baltic Sea and the Taiwan Strait — as signs of rising threats to critical undersea infrastructure.

Subsea fiber-optic cables are essential to global commerce, finance and everyday communications; damage or disruption can produce wide-ranging economic and security consequences. Supporters argue that stronger deterrence, faster repair capabilities and closer international coordination are needed to protect these vital links.

“As the world witnesses an uptick in cable cuts such as in the Baltic Sea and the Taiwan Strait this past year, the United States must position itself to respond to these evolving threats,”
Shaheen said.

If enacted, the legislation would give U.S. authorities new tools to punish perpetrators through sanctions while boosting investments in prevention, monitoring and rapid-response repair operations. The measure emphasizes partnership with allies and international bodies to improve resilience and collective response to attacks on subsea infrastructure.
