Event organiser Bangkok Exhibition Services Ltd (BES) projects the industry will grow 15-20% next year, on par with this year, on the back of economic improvement and tourism recovery.
General manager Justin Pau said the country's mourning after the loss of His Majesty the King has not affected the organisation of fairs and exhibitions in the long term as the overall picture of the Thai economy will not change.
Most major fairs and exhibitions, particularly international ones, have been planned for over a year.
"The market has already adjusted itself and business is now running as usual," he said.
Next year, BES plans to organise two major events, Propak Asia 2017 during June 14-17 and Food & Hotel Thailand during Sept 6-9, both at Bangkok International Trade & Exhibition Center in Bang Na.
For Propak 2017, the company will expand its exhibition space by 30%, and 15% of total booths have been reserved so far.
Propak is an exhibition about processing and packaging food, drink and pharmaceutical products.
"Thailand is a kitchen of the world, producing various foods and there is strong demand for new machines and technologies to process foods," Mr Pau said.
For Food & Hotel Thailand 2017, the fair's space will expand by 10% to serve high demand from food and hotel operators whose businesses are doing well on the back of strong tourism.
In general, Mr Pau said event organisers will prioritise organising new fairs next year, based on the success of events this year, and will not create new events or fair names.
"The exhibition industry is highly competitive and many international event organisers are trying to bring their events from the United States and Europe to Thailand due to lower expenses," he said.
Moreover, international investors are now heading towards Thailand as an investment hub in Asean.
BES itself has expanded event organisation to Myanmar, where it has plans to organise four events this year, and there will be five events next year.
"The event-organising market in Myanmar is expected to expand more after the country has elected a democratic government. It can grow in a range of 5-20% next year but it faces limited exhibition space," he said.
