It is noticeable that all provinces in the Golden and Emerald Triangle regions are active in creating projects within provinces and between provinces and nearby countries. However, the cooperation between provinces in Thailand has not been clearly demonstrated. Thus, some activities created by different provinces may be redundant or have scheduling conflicts and are consequently less effective. Therefore, a policy with specific action plans should be set so that all stakeholders could follow the same policy and strategy. As such, more effective cooperation can be expected. For example, the agreement to establish sister cities among many provinces was made while the activities of each party were not clearly stated and implemented. Trade fairs may be visible activities, but they may not be sustainable. As such, the master plan on which province (in Thai) should be paired as a sister province with which province (in Laos or Cambodia) should be set, including the minimum required activity plans. Then, each province could set up a sophisticated policy and activities that are advanced and capable of being implemented.
