The plan reduces the quarantine period to seven days for fully vaccinated tourists in Phuket, Krabi, Phang Nga, Pattaya and Chiang Mai, said government spokesman Anucha Burapachaisri.
From July 1, vaccinated tourists can visit Phuket without undergoing quarantine.
From October 1, the quarantine measure will be lifted in Krabi, Phang Nga, Pattaya and Chiang Mai.
According to the plan’s timeline, Thailand will lift all quarantine restrictions on foreign travellers next year, Anucha said.
