Chinese Vessel Cuts Taiwan Internet Cable

Taiwan’s coast guard is investigating the Chinese-owned vessel, Shunxin 39, for allegedly severing an undersea internet cable near Keelung Harbor on January 6, 2025. The incident caused minimal disruption as rerouted communications restored service quickly.

This incident adds to previous suspicions of sabotage by Chinese vessels. It highlights Taiwan’s vulnerabilities amid rising tensions with China. Analysts suggest the damage aligns with China’s intimidation strategy against Taiwan, raising concerns about securing critical infrastructure in the region.

How Does the Damage of Undersea Cables Affect Taiwan’s Economy?

Damage to undersea cables threatens Taiwan’s critical digital infrastructure and impacts its economy. Disruptions can break communications and affect sectors like the semiconductor industry, vital to global supply chains.

Experts estimate daily losses of up to $55.63 million during such disruptions, with costs escalating during prolonged outages. Taiwan’s fragile cables make it vulnerable, especially with increased tensions with China. Potential sabotage could have far-reaching effects on the global economy.
