Thailand will not stop its reopening plan despite uncertainty over the Omicron variant and the Tourism and Sports Ministry will also propose more relaxation on alcohol sales.

"Nobody wants another border closure as it was really difficult for us to reopen the country. Our economy still suffers from the crisis, so there will be no more border closures unless we are in a critical situation," said Phiphat Ratchakitprakarn, Tourism and Sports Minister.

He said international travellers during the first 29 days of reopening numbered over 100,000.

The ministry expected 300,000-400,000 tourists would visit Thailand by year-end, thanks to the winter season.

However, the plan to replace RT-PCR tests with antigen test kits for the Test and Go scheme from Dec 16 has to be postponed until there is more clarity on the Omicron variant.

Mr Phiphat said he will discuss with the cabinet today about allowing the sale of alcohol in blue zone areas until after midnight during year-end celebrations and unlocking sales from 2-5pm as the current rules don't permit booze sales during those hours.

Mr Phiphat said the Tourism Authority of Thailand (TAT) will organise countdown events in five regions including Ayutthaya, Nakhon Ratchasima, Chiang Mai, Phuket and Chonburi.
