The killing of 39 people in a container truck in England last month was described as "a serious humanitarian tragedy" after British police said all the victims were believed to be Vietnamese. .
"We are deeply saddened and extend our deepest sympathy to the families of the victims, and we hope to overcome this enormous loss soon," said ministry spokeswoman Lu Thi Thu Hang in a statement.
"We hope that the British side will complete the investigation soon to bring to justice those responsible for this tragedy," she said.
British police said on Friday they believed all 39 immigrants whose bodies were found in a truck in Essex last week had Vietnamese nationality.
"At this time, we believe all the victims are Vietnamese nationals and we are in contact with the Vietnamese government," Essex police assistant Tim Smith said in a statement on Friday evening.
Essex police said they could not identify the victims at this time, but indicated that they had reached out to many of the victims´ families.
When police found the bodies in the early hours of October 23, police said the migrants were Chinese. This assumption was questioned last week, with many Vietnamese families reporting missing loved ones who feared to be dead.
Local media reported that 28 families reported missing relatives in the Vietnamese provinces of Ha Tinh and An An.
Vietnamese authorities have since launched a campaign against human trafficking and carried out six arrests last week, two of which are believed to be linked to the deaths in a container truck in Britain.
Hundreds of Vietnamese citizens are smuggled into Britain every year, according to the charity Ikbat.
