Chinese ship spotted lurking over Taiwan-US undersea cables — 'research vessel' seen loitering above the 8,000-mile Pacific Light Cable Network fiber-optic system

A video circulating online depicts a Chinese-flagged research vessel approaching a crucial undersea cable connecting Taiwan to the US. The vessel, roughly 200 feet in length, was reportedly warned by Taiwan's Coast Guard to alter its course. The cable in question is the 8,000-mile Pacific Light Cable Network (PLCN), a fiber-optic system linking Taiwan, the US, and the Philippines.

This incident has sparked concerns about potential intelligence gathering by the Chinese vessel. Windward, a maritime analysis platform, corroborated that the presence of such vessels over these cables often indicates spying activities. The PLCN, originally intended for a route to Hong Kong, was rerouted due to American apprehensions over Chinese surveillance.

Despite being classified as 'civilian,' China's military-civil fusion policy renders this distinction ambiguous. This particular Chinese vessel has a history of appearances in disputed territories, including the Paracel and Spratly Islands, claimed by China, Taiwan, and various Southeast Asian nations. The concern over internet cable espionage and potential sabotage is not unfounded, as Chinese-flagged vessels have been involved in similar incidents in the past, including the Baltic Sea and around Taiwan.

Geopolitically, Taiwan plays a pivotal role in the global technology and semiconductor sectors, primarily due to the operations of TSMC. Consequently, undersea cables have become a vital infrastructure for nations, but also a potential weak point susceptible to acts of sabotage.
