The 41, who came from Shanghai, underwent strict checks by public health officials before being sent to state quarantine for 14 days.
The second group, comprising more than 100 tourists from Shanghai and Guangzhou, are expected to arrive on October 26 and 28.
Tourism Authority of Thailand governor Yuthasak Supasorn said officials were still considering where flights carrying future STV tourists from Europe would land, as it would depend on where the tourists have booked their 14-day mandatory quarantine.
“I confirm that all foreigners who arrive will have to strictly comply with health measures. They will be allowed to travel around the country only if they are clear of infection once the quarantine period is over. However, each tourist will be required to have a tracker app,” Yuthasak said.
