This legislation, titled the Strategic Subsea Cables Act of 2025, seeks to bolster the United States Government's strategic coordination regarding the security, installation, maintenance, and repair of international subsea fiber-optic cables. Recognizing these cables as the backbone of the global internet, the bill emphasizes their importance for national security and economic interests. Title I focuses on international coordination and engagement . It directs the Secretary of State to increase U.S. engagement in the International Cable Protection Committee (ICPC) and requires annual reports on this engagement, including how the People's Republic of China leverages its involvement. Crucially, it authorizes the President to impose sanctions , such as property blocking and visa restrictions, on foreign persons responsible for damaging subsea cables in a manner that undermines U.S. national security interests. Furthermore, Title I mandates annual reports on the subsea fiber-optic cable activities of the People's Republic of China and the Russian Federation, detailing their manufacturing capabilities, vessel activities, and any anomalous behavior around cable networks. It also stresses the importance of engaging foreign partners to strengthen cable security, maintenance, and repair through diplomatic efforts and resource commitment. Title II addresses the need for Department of State subsea fiber-optic expertise by requiring the assignment of at least two full-time personnel to the Bureau for Cyberspace and Digital Policy. These individuals will support interagency engagement on cable protection, resilience, and international coordination, ensuring dedicated diplomatic focus on this critical infrastructure. Finally, Title III concentrates on coordination, construction, and repair within the U.S. government. It mandates the establishment of an interagency committee to lead efforts in protecting and improving cable resilience, facilitating permitting, and addressing related matters. This committee will develop an interagency concept of operations for partnering with non-federal entities and streamline permitting processes. The bill also requires strategies to analyze subsea cable cuts and outages, identify trends, attribute malicious damage, and inform future risk mitigation efforts. To enhance overall security, it strengthens information sharing between U.S. government agencies and private sector actors on subsea fiber-optic cable threats, including both classified and unclassified intelligence, to prevent breaches and mitigate adverse effects.
