Thailand plans to end Covid quarantine requirements for fully vaccinated travellers from at least 10 low-risk nations from 1 November, officials say.
PM Prayuth Chan-ocha admitted that "this decision comes with some risk" - but it is seen as a key step to revive the country's collapsed tourism sector.
The 10 nations seen as low risk include the UK, China, Germany and the US.
The country has been recording more than 10,000 positive infections daily since July.
It has fully vaccinated around 33% of its almost 70 million people. Half the population has received one dose.
Mr Prayuth said Thailand would also allow entertainment venues to reopen on 1 December and permit alcohol sales.
The government had earlier planned to open only Bangkok and several provinces for foreign tourists on Nov 1. The other provinces are Chon Buri (Pattaya city, Bang Lamung district, and Sattahip district), Phetchaburi (Cha-am district), Prachuap Khiri Khan (Hua Hin district) and Chiang Mai (Muang, Mae Taeng, Mae Rim and Doi Tao districts).
Monday's announcement indicated that the reopening would cover all parts of the country.
Thailand will begin with at least 10 nations, including Singapore, Germany, China, the United Kingdom and the United States.
