Vietnam has called on countries around the world to step up the fight against human trafficking.
It comes after UK police confirmed that they believe all 39 people found dead in a truck container in Essex last week were Vietnamese nationals.
It comes as a 23-year-old man is facing extradition from Ireland to the UK to face charges over the discovery.
Meanwhile, a manhunt is continuing for two brothers from County Armagh who are wanted in connection with their investigation.
In a statement, Vietnam Foreign Affairs Ministry spokesperson Le Thi Thu Hang said: “Vietnam strongly condemns human trafficking and considers it a serious crime subject to strict penalties.”
“Vietnam calls upon countries in the region and around the world to step up cooperation in combating human trafficking in order to prevent the recurrence of such tragedy.
She said Vietnamese authorities remain hopeful that UK police can complete their investigation as soon as possible and “bring those responsible for this tragedy to justice.”
“This is a serious humanitarian tragedy,” she said.
“We are deeply saddened by the incident and wish to extend our heartfelt condolences to the victims’ families.
“We wish they may soon overcome those tremendous pain and losses.”
