The JCG said the vessel’s tracking signal was lost around 9:40pm (local time).
The two Vietnamese nationals were among the 12-member crew of the 1,925-tonne ship. Ten others included three Myanmar and seven Chinese.
The accident killed one sailor and six remain missing. Four others were rescued by the JCG on October 13 morning, it said.
The fate of the Vietnamese sailors remain unknown.
