“We don’t do anything wrong, for sure,” Mr Toan told ABC, the Australian network. “I really take care of all of the customers [who] stay with our hotel and our hostel.”
Ms White, from Orpington in the London borough of Bromley, was taken to hospital following a night out with friend Bethany Clarke, a healthcare worker who is also from Orpington.
It is not clear when Ms White died or her cause of death. Her family were unavailable for comment when approached by The Telegraph on Thursday.
Ms Clarke, who was also treated in hospital, said her “liver started to shut down” after drinking free shots offered by one of the bars in Vang Vieng.
She warned other travellers to “avoid all local spirits” on a Facebook group for backpackers in Laos.
“Urgent – please avoid all local spirits,” she wrote. “Our group stayed in Vang Vieng and we drank free shots offered by one of the bars.
“Six of us who drank from the same place are in hospital currently with methanol poisoning,” she added.
A Foreign Office spokesman said on Thursday: “We are supporting the family of a British woman who has died in Laos, and we are in contact with the local authorities.”
