I. IntroductionImproving the value of exports is the primary objective of Thailand's international trade policy. The Association of Southeast Asian Nations (ASEAN) Economic Community (AEC) was established as an effective cooperative strategy to gain market advantages through regional market integration. Thailand aims to benefit from trade agreements by building networks and initiating partnerships with neighboring countries. Currently, Thailand's cross-border trade in the Greater Mekong Subregion (GMS) plays a crucial role in globalization as it facilitates quick and convenient trade and investment. Countries seek new export markets to disperse the risk of domestic market concentration, as evidenced by economic recessions affecting many developed countries, such as the United States, Japan, China, and various European Union member countries. Thailand must adapt to global economic changes by seeking new markets to increase foreign investment and stimulate the Thai economy. Additionally, GMS markets could offer a source of production and a channel for product distribution. Recently, the Thai government has focused on developing its cross-border markets, the value of which has steadily increased. Divided by the Mekong River, the five countries adjacent to Thailand are Laos, Cambodia, Vietnam, Myanmar and China. Trade values ​​in the GMS have increased considerably because the emergence of open economies and the development of economic policies have attracted foreign interests in trade and investment. From the information on the value of Thailand's cross-border trade exports with GMS countries, exports from Thailand dominated GMS countries, especially Myanmar, Cambodia and Laos. Thai exports to Myanmar and Laos stood at around… middle of paper… 22%, although the growth rate of exports from Thailand to China was slightly lower at 21% per year. The empirical results provide a reference for researchers studying Thailand's international trade position and investors seeking cooperation opportunities in the AEC. The strategies involved in the development of Thailand's import and export industries have been facilitated through trade agreement activities, such as networking and collaboration with neighboring countries. Thailand has adapted by improving ASEAN's manufacturing base in both manpower and technology and developing distribution channels through transportation and logistics security in the sample used in establishing new joint ventures in GMS countries to promote participation of all the sectors involved in the development of visible and tangible policies. on the joint study of feasibility and advantages.
