Taiwan’s Coast Guard Administration has detained the Chinese-crewed cargo vessel Hong Tai 58, a Togolese-flagged ship with Chinese ownership, on suspicion of deliberately severing the Taiwan-Penghu No. 3 (TP3) submarine cable — a critical communications link between Taiwan’s main island and the outlying Penghu archipelago. The incident, which occurred in the pre-dawn hours of a February morning, produced the first successful prosecution of its kind under Taiwan’s Telecommunications Management Act. The captain, a Chinese national identified as Wang, received a three-year prison sentence. Both the initial trial and appeal upheld the conviction.
