Convenience stores and markets could open until 10pm and also reopen their amusement zones.
Cinemas, eateries, theatres, stadiums, public parks and shopping centres could stay open until 10pm.
Daycare centres for elderly people could reopen and all public transport vehicles could utilise all passenger seats.
Trade, convention and exhibition centres and the likes at hotels and department stores could organise meetings of up to 500 people, but food would have to be in individual servings, people must wear face masks and meetings be limitied to two hours duration and end by 10pm.
Shopping centres, except those in dark-red zones, will be able to reopen game arcades but not water parks or amusement parks.
Limits for participants in gatherings will be raised to 50 in dark-red zones, 100 in red zones and 200 in orange zones.
Entertainment places will remain closed, including pubs, bars and karaoke shops, because of the high risk of disease transmission, Dr Taweesilp said.
