The Tourism and Sports Ministry expects to spend 500-600 million baht on concerts in Bangkok and Phuket after it was confirmed that two artists -- 'Lisa' and Andrea Bocelli -- will perform.

"Bringing both artists to Thailand is beyond economic value, particularly Lalisa 'Lisa' Monaban, the young Thai K-pop singer, who is a huge inspiration for the youth of the country," said Tourism and Sports Minister Phiphat Ratchakitprakarn.

He said both singers have been confirmed to perform in Thailand, with the opera star Bocelli's performance set to take place in Bangkok at Sanam Luang, with the Grand Palace as the background.

Lisa's show might be held in Phuket at Sarasin Bridge, the road link from the mainland to the island, said Mr Phiphat.

He said the event should be co-hosted by the government and the private sector, with 200 million baht coming from the state budget, and 300-400 million from private sponsorship.

The Tourism Authority of Thailand (TAT) is awaiting the artists' availability for dates and time slots. A New Year's celebration is the most preferred date for the TAT.

"With their busy work schedules, we have to wait and see whether they can come for the countdown," said Mr Phiphat.

The Centre for Covid-19 Situation Administration approved on Thursday entry without quarantine for vaccinated arrivals from some countries starting on Nov 1.
