Critical Undersea Infrastructure Resilience Initiative Act

This bill establishes the Taiwan Undersea Cable Resilience Initiative to protect undersea communication cables critical to Taiwan's security and economy. It directs the State Department to coordinate with defense and maritime agencies to create real-time monitoring systems, rapid repair protocols, enhanced surveillance of suspicious vessels near Taiwan, and international partnerships for cable protection. The bill also authorizes U.S. sanctions - including property blocking and visa bans - against individuals or entities from China found responsible for sabotaging cables near Taiwan. It requires semiannual reports to Congress detailing cable incidents and U.S. responses.
