Chinese Research Vessel Activity Near Pacific Cables Raises Concerns
Chinese Vessel Maneuvers Over Pacific Light Cable Network
A Chinese research vessel has been observed hovering over undersea cables connecting the United States with Taiwan and the Philippines. Analysts suggest this behavior aligns with intelligence gathering operations. The vessel, identified as China-flagged, had been tracked by the maritime analysis platform Windward, operating at a slow speed directly over the Pacific Light Cable Network located in the Philippine Sea. This cable system spans 8,000 miles of trans-Pacific fiber-optic connections.
The vessel’s activity is set against the backdrop of continuous Chinese pressure on Taiwan. Taiwan serves as a key U.S. trading partner and produces over 90% of the world’s advanced microchips. Beijing considers the island a part of its territory and has maintained that force is an option for unification.
Response to Allegations
Chinese authorities have refuted claims that their ships have intentionally damaged undersea cables. They have accused Taiwan and Western governments of premature conclusions before investigations conclude. Newsweek contacted Windward and the respective foreign ministries in China and Taiwan for comments via email.
Maritime Intelligence Signals
Windward stated, “Slow-speed movement over critical undersea infrastructure is one of the clearest behavioral signals in maritime intelligence. Cables don’t move. Vessels that hover over them get noticed.”
Submarine cables manage approximately 99% of intercontinental internet traffic. Although the specific name and MMSI of the ship were censored in the report, Windward noted this same vessel had previously operated in the disputed Paracel Islands and the Spratly Islands. These areas have territorial disagreements involving China, Vietnam, the Philippines, and other governments. It also reached the Bay of Bengal and waters off Sri Lanka.
Geopolitical Tensions
The cable received significant attention in 2020 when U.S. regulators halted a proposed Hong Kong connection. Concerns were raised regarding potential risks of exposure of American data to Chinese intelligence. The project was adjusted to connect solely the U.S., Taiwan, and the Philippines.
Suspicion endures regarding Chinese civilian research vessels collecting intelligence in neighboring countries’ maritime zones, facilitated by Beijing’s military-civil fusion strategy. Data obtained can be shared with the People’s Liberation Army upon request.
Heightened Pressure on Taiwan
Chinese-flagged vessels have been associated with multiple cable incidents recently, including suspected sabotage in the Baltic Sea and disruptions around Taiwan. The presence of a Chinese survey vessel over undersea cables is sensitive given strained relations between China and Taiwan.
China has intensified pressure on Taiwan’s reluctant government, with military flights over the Taiwan Strait’s median line and increased coast guard patrols near Taiwan’s Kinmen Islands. Since June, China has deployed coast guard and research vessels east of Taiwan, purportedly to assert presence in areas crucial to Taiwan’s strategic interests.
