The government is being asked to work out new tax incentives to promote investment in amusement and theme parks, as existing measures are proving inadequate to lure investors.
"Thailand has set a lofty plan to boost tourism income to 2 trillion baht by 2015," said Suwat Sidthilaw, the tourism and sports permanent secretary.
"The government needs to improve in many areas including support for tourism-related facilities, easing visa extensions for long-stay visitors and better safety measures."
The Board of Investment now offers tax privileges to amusement park start-ups that invest more than 500 million baht.
The privileges include import tariff waivers for machinery and a corporate tax exemption for five years in zone one (Greater Bangkok), seven years in zone two (12 other large provinces) and eight years in zone three (remote low-income areas).
The private sector has long pressed the government to modify conditions for capital investment, saying the 500-million-baht requirement as too hefty.
Mr Suwat said the Finance Ministry should also consider cutting import tariffs for playground equipment and toys, now at 25%.
The government has already told relevant agencies to study the possibility of extending visas for long-stay visitors from the current six months to put it on a par with countries such as Malaysia, which offers a 10-year visa, but nothing has come of it.
Mr Suwat said revenue from foreign visitors in the first nine months of this year reached 863 billion baht, up by 23% year-on-year, with foreign tourists numbering 19.7 million, also up by 23%.
The Tourism and Sports Ministry expects the number of inbound tourists to hit 26 million by year-end, outpacing the previous forecast of 20 million by 30%.
