Casinos and other related attractions will greatly increase the number of foreign tourists coming into Thailand according to a senior executive of an online travel agency. As countries dependent on tourism move closer to legal gaming, only certain forms of gambling are allowed in Thailand. This includes state-regulated horse racing and official lotteries but illegal activities persist. Previous attempts to legalize gambling failed due to conservative and popular opposition to opening casinos. The lack of legal casinos in Thailand means the country is losing out on state revenue and is a huge boost to tourism, the government says.
