The discovery of the bodies was made on Wednesday after emergency services were alerted to people in a truck container on an industrial site in Grays, about 32km east of central London. Police have said they believe the dead were Chinese but Beijing said the nationalities had not yet been confirmed. Chinese and Vietnamese officials are now both working closely with British police, their respective embassies have said.
