Nine Vietnamese men are missing after their cargo ship collided with an unknown vessel and sank in the waters off the country's southern coast early on March 28, 2017, according to the Vietnam Maritime Search and Rescue Center (MRCC).
Two of 11 crew members have so far been rescued from the Hai Thanh 26, which sank around midnight about 44 nautical miles to the east of Vung Tau City in Ba Ria-Vung Tau Province.
The MRCC has deployed two surveillance ships and has requested a nearby oil tanker, Petrolimex 14, which found the two members of the sunken ship on a raft, to assist the rescue effort.
The centre is also coordinating with other ships operating in the area to search for the nine missing crew members.
Another similar incident recently took place in the region when two vessels sunk off the coast of the Philippines at the start of this year.
