The government is likely to allow alcohol to be served at restaurants, concerts and closed-venue sports to resume and saunas to reopen in the fourth phase of lifting coronavirus restrictions from June 15.

Taweesilp Visanuyothin, spokesman for the Centre for Covid-19 Situation Administration (CCSA), said on Wednesday that the CCSA will consider the changes on Friday.

The draft proposal would also allow international and cram schools to reopen and governmental organisations to resume holding meetings.

Restaurants and hotels would be allowed to serve alcohol. However, the relaxation measure would still exclude pubs, bars and karaoke joints, which are considered to pose a greater danger of coronavirus disease transmission, Dr Taweesilp said.

Concerts would be allowed on condition that audiences did not sing along too much, because that would spray droplets, Dr Taweesilp said.

On public transport, two passengers could sit next to each other as long as one seat was empty on each side. 

Health-orientated spas and saunas could reopen provided each customer had at least five square metres of space. Soapy massage parlours would remain closed, Dr Taweesilp said.

Amusement parks, playgrounds, water parks and swimming pools could reopen. 

Group exercises would be permitted at parks and sports fields as long as each participant had at least five square metres of space, with a maximum of 50 people per group.

Game arcades inside malls could reopen. Each player would be given a maximum of two hours.

The CCSA would consider the measures on Friday and the relaxation was likely to begin next Monday.
