Discourse about the minority groups in the highlands who are “Others” and for over 200 years have been under the political domination of the kingdom and modern states. Changes in the position of the hilltribes have influenced the change in meaning in order to understand the highlander’s culture. This discourse is related to the meaning of discourse carried out by other ethnic groups with the aim of getting the highlander’s participation. (p.1) From the case of the Karen in M Village on Doi Inthanon, the government has advertised and promoted eco tourism projects with community participation. This project is rarely accepted by the people in the community. Lessthan half the villagers were involved in this project. The reason that they did not accept it is that they do not want to support what the government has advertised. However, they cannot avoid cooperation with the coordinators who are villagers. For the ones who accepted this project, it is because it presents them as rustic hilltribes which is the image that the government has promoted. From the discourse of the Karen who love peace, elephants, nature and live in the forests, it is used and presented by the Karen themselves under the eco tourism project supported by the government. This discourse is also a means to support the culture and participate with other ethnic groups and a part of the Thai government. Even though this is the government’s aim, it does not project the minority group’s voice and ideas as they are perceived and expanded. Hinton noted that the ethnic groups define themselves far away from politics, economics and social issues. (p.18-19)
