A Chinese research vessel has been observed near undersea cables connecting the U.S. with Taiwan and the Philippines. Analysts suggest this behavior indicates intelligence gathering activities.
Maritime analysis platform Windward monitored the 200-foot China-flagged vessel hovering at a slow speed directly over the Pacific Light Cable Network in the Philippine Sea. This network is an 8,000-mile trans-Pacific fiber-optic cable system. The vessel’s presence occurs amidst ongoing Chinese pressure on Taiwan, a key U.S. trading partner and a significant producer of advanced microchips. Beijing, which claims Taiwan as its territory, has not ruled out forceful unification efforts.
Chinese authorities have denied allegations that their ships intentionally damaged undersea cables, accusing Taiwan and some Western governments of making hasty conclusions before thorough investigations. Newsweek has reached out to Windward and the Chinese and Taiwanese foreign ministries for comments via email.
Signs of Intelligence Gathering
Windward states that “slow-speed movement over critical undersea infrastructure is a clear indicator of maritime intelligence operations.” Submarine cables facilitate about 99 percent of intercontinental internet traffic.
Although the ship’s name and MMSI were concealed in the report, Windward identified the same vessel as having operated repeatedly in disputed regions such as the Paracel Islands and the Spratly Islands. It has also ventured to the Bay of Bengal and waters off Sri Lanka.
The cable system first became a geopolitical issue in 2020 when U.S. regulators blocked a planned Hong Kong connection over national security concerns. The fear was that American data might be exposed to Chinese intelligence. Consequently, the project was reconfigured to connect only the U.S., Taiwan, and the Philippines.
The Chinese government is believed to employ civilian research vessels for intelligence collection and maritime surveys in neighboring countries’ zones. Information from these vessels can be shared with the People’s Liberation Army under Beijing’s military-civil fusion policy.
China’s Increased Pressure on Taiwan
Chinese-flagged vessels have been associated with cable incidents in recent years, including suspected sabotage in the Baltic Sea and damage to cables around Taiwan. The presence of a Chinese survey ship over undersea cables is notable during tense relations between Beijing and Taipei.
China’s pressure campaign against Taiwan includes near-daily military flights over the Taiwan Strait median line and increased coast guard patrols near Taiwan-held Kinmen Islands. Since June, Beijing has sent coast guard and research vessels into waters east of Taiwan, a strategy analysts say aims to normalize China’s presence in Taiwan’s strategic rear.
