Government Spokesman Anuchai Burapachaisri said that the list would also be used to consider reduction of the quarantine period from the current mandatory 14 days.
Danucha Pichayanan, secretary-general of the National Economic and Social Development Council, said that it was important to set up clear criteria to grant foreigners entry.
The Centre for Economic Situation Administration at a recent meeting reportedly discussed the private sector's proposal to ease restrictions on the entry of foreign investors and business persons, including a shorter quarantine period.
The Public Health, Tourism and Sports and Foreign ministries are jointly drawing up clearer rules on this.
