Bangkok is banning indoor dining and gatherings of more than 20 people as it faces a COVID surge.
The Thai capital is also closing down constructions sites and sealing off workers' quarters in 10 provinces.
Department stores and malls in Bangkok can stay open until 9 p.m., but restaurants can only do to-go orders.
The measures will stay in place for 30 days.
COVID numbers have doubled recently with Thailand reporting 3,995 confirmed cases and 42 dead in the last 24 hours.
