The result of the first Covid-19 test on arrival for 39 Chinese tourists who travelled using the special tourist visa reported no positive cases.
Another two groups from China are scheduled to arrive on Oct 26 and Oct 28, while Scandinavian travellers are ready to arrive in November, said Phiphat Ratchakitprakarn, the tourism and sports minister.
He said the ministry has not received inbound requests from other countries.
The ministry plans to consider the consequences from the first stage of reopening.
If a new flow of tourists arrive without any positive cases, the government is ready to implement a more relaxed quarantine, but this requires approval from the Centre for Covid-19 Situation Administration first, said Mr Phiphat.
"Europe now faces a second wave," he said. "The Tourism and Sports and Foreign ministries will allow tourists from low-risk cities with zero new cases for more than 30 days."
