Eight sailors including three Vietnamese were saved from their South Korean fishing boat after it caught fire and sank in Japanese waters early Tuesday.
Japanese rescuers said they sent out rescue teams after receiving requests from Vietnamese and South Korean authorities, as the 2006 Nam Seong sank at 3:20 a.m. around 250 kilometers off Japan's southern coast.
The 29-ton boat was carrying three Vietnamese and seven South Koreans, the news website VnExpress reported, citing a statement made by Vietnam's Foreign Ministry.
Two South Korean sailors are still missing.
The ministry has ordered the Vietnamese embassy in Japan to work with local authorities to provide the sailors with necessary treatment and other essentials while waiting for the boat owner to intervene.
