Taiwan suspects that a Chinese-owned cargo vessel damaged an undersea cable near its northeastern coast on Friday, in an alleged act of sabotage that highlights the vulnerabilities of Taipei’s offshore communications infrastructure.
The ship is owned by a Hong Kong-registered company whose director is Chinese, the Financial Times reported on Sunday.
An unidentified Taiwanese official cited in the report described the case as sabotage.

The incident followed another Chinese vessel’s suspected involvement in the breakages of data cables in the Baltic Sea in November last year. While fishing trawlers are known to sometimes damage such equipment, nation states have also been accused of deliberate sabotage, although it can be difficult to prove.
“This is why Taiwan needs to build its telecommunications resilience, and strengthen its situation awareness in the surrounding waters,” Institute for National Defense and Security Research postdoctoral researcher Hsu Chih-hsiang (許智翔) said. “Otherwise, the system would be easily undermined, and it would be difficult to hold the suspect accountable.”
China’s Taiwan Affairs Office did not immediately respond to a request for comment.
Previously, the Coast Guard Administration (CGA) named Cameroon-flagged Shunxing 39 as the suspected offender without identifying its ownership.
Officers tried, but were unable to board the vessel for investigation due to rough weather, the CGA said.
The damage did not affect connection, because data were immediately rerouted to other cables, Chunghwa Telecom said in a statement on Saturday.
The company co-owns the cable system along with AT&T of the US and regional operators including Japan’s Nippon Telegraph & Telephone and China Telecom, the Financial Times said.
Taiwan has asked South Korea for help with the investigation, as the ship is due to arrive in Busan in the coming days, it said.
The integrity of undersea cables has been a rising security concern in Taiwan. As recent as in 2023, telecommunication services in Lienchiang County (Matsu) were disrupted for months after Chinese fishing vessels cut the cables.
To back up connections in the event of a failure, the Taiwan Space Agency in 2023 said it intends to launch its first self-made low Earth orbit communications satellite next year and at least one more by 2028.
The Coast Guard Administration (CGA) and Chunghwa Telecom yesterday confirmed that an international undersea cable near Keelung Harbor had been cut by a Chinese ship, the Shunxin-39, a freighter registered in Cameroon. Chunghwa Telecom said the cable had its own backup equipment, and the incident would not affect telecommunications within Taiwan. The CGA said it dispatched a ship under its first fleet after receiving word of the incident and located the Shunxin-39 7 nautical miles (13km) north of Yehliu (野柳) at about 4:40pm on Friday. The CGA demanded that the Shunxin-39 return to seas closer to Keelung Harbor for investigation over the
National Kaohsiung University of Science and Technology (NKUST) yesterday promised it would increase oversight of use of Chinese in course materials, following a social media outcry over instances of simplified Chinese characters being used, including in a final exam. People on Threads wrote that simplified Chinese characters were used on a final exam and in a textbook for a translation course at the university, while the business card of a professor bore the words: “Taiwan Province, China.” Photographs of the exam, the textbook and the business card were posted with the comments. NKUST said that other members of the faculty did not see
The Taipei City Government yesterday said contractors organizing its New Year’s Eve celebrations would be held responsible after a jumbo screen played a Beijing-ran television channel near the event’s end. An image showing China Central Television (CCTV) Channel 3 being displayed was posted on the social media platform Threads, sparking an outcry on the Internet over Beijing’s alleged political infiltration of the municipal government. A Taipei Department of Information and Tourism spokesman said event workers had made a “grave mistake” and that the Television Broadcasts Satellite (TVBS) group had the contract to operate the screens. The city would apply contractual penalties on TVBS
An apartment building in New Taipei City’s Sanchong District (三重) collapsed last night after a nearby construction project earlier in the day allegedly caused it to tilt. Shortly after work began at 9am on an ongoing excavation of a construction site on Liuzhang Street (六張街), two neighboring apartment buildings tilted and cracked, leading to exterior tiles peeling off, city officials said. The fire department then dispatched personnel to help evacuate 22 residents from nine households. After the incident, the city government first filled the building at No. 190, which appeared to be more badly affected, with water to stabilize the
