In 2002, the number of Thailand’s outbound tourists totalled 2,249,639, which was an increase of 11.89%. This is considered a rather high expansion compared to the growth rate of the previous year, which equalled 5.33%. This is a result of the improved economy of Thailand, which caused a psychological effect on Thai tourists. They were encouraged to spend more money on overseas trips. Regional trips to Malaysia, Singapore, and China, respectively, were the most popular among Thai tourists. Various countries in East Asia adopted a tourism promotional policy for the economic improvement in each country; therefore, there was huge marketing and public relations in Thailand, especially by our neighbouring countries such as Malaysia and Singapore. China is a very attractive destination for the world’s tourists, as it is a new country that is abundant with things to be discovered and is also Asia’s giant economic country. These factors encouraged more Thai tourists to travel to the mentioned destinations.
