A general cargo ship has sunk in the Taiwan Strait, but all eight crew members were rescued.
Taiwanese broadcaster PTS said an unnamed Mongolia-flag vessel began to take on water through a hole in the bottom of the hull on Monday.
The ship sent out a distress call when it was 90 nautical miles west of Kaohsiung, later capsizing to the port side.
The seafarers, all wearing lifejackets, reportedly fell into the sea, but Taiwan Coast Guard helicopters came to the rescue, winching the men to safety.
The vessel then sank quickly, PTS added.
One of the crew members was taken to hospital suffering from hypothermia.
Video footage shows seafarers gathered at the stern of the vessel as it lists.
One is then seen being lifted into a chopper from what appears to be a couple of lifeboats.
An investigation has begun into the accident.
AIS data suggests the most likely candidate is the 1,600-dwt Sunshine (built 1985), the ex-Hao Feng, which was out of range on 15 January, stopped in the Taiwan Strait.
The vessel is owned by NCS Properties of Malaysia, which could not be contacted.
The Sunshine was last detained following a port state control inspection in 2019 in China with 17 deficiencies.
Grounds for detention included faults with charts, the emergency fire pump, lifeboats and weathertight cargo ports and doors.
