Taiwan’s coast guard has detained a Togo-flagged cargo vessel and its eight-member Chinese crew following an incident involving a cut undersea internet cable. The cable, which connects Taiwan to its outlying Penghu Islands, was found severed after the ship, named Hong Tai, had been lingering near the cable’s location in the southwestern coastal waters since Saturday evening. When the vessel dropped anchor early Tuesday, multiple alerts from Taiwan’s coast guard went unanswered, prompting immediate action.
Chunghwa Telecom, Taiwan’s leading telecom provider, detected the disconnection shortly after the ship anchored. In response, authorities intercepted and boarded the vessel, then escorted it to Tainan port for further investigation. Taiwanese officials have not yet determined whether the cable was intentionally cut or if the incident was an accident. The matter is currently under investigation by prosecutors, following national security-level guidance.
The incident has raised significant concerns about potential “gray zone” operations—a term used to describe coercive or subversive activities that fall short of full-scale war. Taiwan’s coast guard has stated that further probing is needed to determine whether the act was a deliberate case of sabotage or a mere accident. Meanwhile, Beijing has dismissed the incident as a routine maritime accident. Zhu Fenglian, spokesperson for China’s Taiwan Affairs Office, remarked that such damage to undersea cables is common, occurring over 100 times a year globally. He accused Taiwan’s ruling Democratic Progressive Party of exaggerating the event for political gain, a claim that has only fueled further debate.
This latest episode is not an isolated event. Over the past few years, Taiwan has witnessed several incidents of suspicious damage to undersea communication cables. In January, a Chinese-linked cargo vessel was suspected of severing an international cable off Taiwan’s northern coast, and in 2023, similar incidents occurred in the Matsu archipelago, causing temporary internet blackouts. These recurring events have heightened fears of covert activities aimed at undermining Taiwan’s connectivity and its strategic communication infrastructure.
The growing concerns come at a time when Taiwan is under increasing pressure from Beijing, which claims the self-ruled democracy as part of its territory and has repeatedly warned of using force if necessary. With the global digital economy heavily reliant on stable communications—over 95% of internet traffic flows through undersea cables, according to international experts—any disruption poses significant risks not only to Taiwan but also to global trade and commerce, which depend on approximately 1.3 million kilometers of such cabling.
The detainment of Hong Tai has put a spotlight on the vulnerability of critical infrastructure and the potential for targeted actions to disrupt communication networks. While the investigation continues, Taiwan’s authorities are urging caution and reinforcing their commitment to protecting their maritime assets. As the situation unfolds, both regional and global stakeholders will be closely watching for any signs that these incidents may be part of a broader strategy to destabilize the region’s digital and economic stability.
In summary, the detention of the cargo ship underscores the complexities and geopolitical risks associated with maintaining secure undersea infrastructure in an increasingly volatile global environment.
