More than 30% of tourism-related businesses have exited the market, with many set to follow, according to the Tourism Council of Thailand (TCT).

Chairat Trirattanajarasporn, president of the TCT, said the tourism industry predicts a further deterioration after six months of the coronavirus crisis, as many related businesses are ending their operations or selling off assets, choosing not to wait for an uncertain recovery.

He said the main types of businesses affected by the crisis are tour operators, bus services with a small vehicle fleet, restaurants, souvenir shops and hotels that used to focus on foreign tour groups, especially the Chinese market.

Mr Chairat said the TCT is in the process of collecting the exact number of members fleeing the sector, which he believes should amount to more than 30% in the first half of the year, as Thailand continues to close the borders to international tourists.

The Tourism Department said 1,111 tour operators in the January-June period gave up their licences.

If travel bubbles cannot be implemented this year, more than 30% of outbound operators will have to permanently shut down their business, said Thanapol Cheewarattanaporn, president of the Thai Travel Agents Association.

At present, most operators have delayed making any decision as they are waiting for further details on travel bubble agreements with other countries. After the infections of an Egyptian airman in Rayong and the daughter of a Sudanese diplomat were detected, these agreements may take even longer to come about.

"The domestic market has become a priority market for tour operators who want to maintain business while waiting for borders to reopen," Mr Thanapol said.
