Sugree Sithivanich, TAT Deputy Governor for Marketing Communications, said only Israel, Slovak, Russia advise a more serious warning to level 3 to avoid non-essential travel.
TAT has been reporting the country's situations through its website as well as to its domestic and overseas offices and related associations to inform facts to travellers in order that they use the information to decide their travel to Thailand.
Mr Sugree said his organisation is also preparing other public relations means in case of emergency to protect the country's image.
Tourism promotion plans continue as planned, he noted, such as His Majesty's birthday celebrations on Dec 5 upcountry and New Year countdown celebrations at CentralWorld Department Store in Bangkok.
Mr Sugree said the number of tourists targetted at the end of this year could still be reached and has not been readjusted at 26 million.
