This paper explores the roles of foreign language in business administration, investigates managerial perspectives and studies the problems of foreign language usage in communication to discover modes of developing employee's foreign language ability and to investigate the students' opinions concerning the roles of foreign languages in business administration in Thailand. In-depth, face-to-face qualitative interviews were employed. The results indicated that foreign languages play significant roles in import and export companies. In the managers' point of view, foreign languages are very important to their businesses, especially for communication with customers, other companies and suppliers. The problems in some companies might happen because of differences between customers. The problems also come from both senders and receivers who lack knowledge of foreign languages. The informants stated that organizations should invite professional trainers to help improve foreign language skills in vocabulary and conversation in particular.

Language plays an imperative role in business as a means and a source of power. It is particularly important in the tourism industry when international customers may be unable to communicate directly with service providers in the receiving country, and this has a direct effect on the level of satisfaction that they enjoy during their experience. To address this issue, countries attempt to various degrees to manage their labour markets so as to produce a number of graduates from secondary and tertiary level educational institutions commensurate with the demand from the sector. However, this is quite a young industry at the global level, and it is not clear to what extent the number and quality of such graduates with international language ability will be required. This paper studies the comparative extent of such education at the tertiary level of individuals in both Thailand and Malaysia. It aims to compare the number and variety of people being trained in the tourism and hospitality industry and the extent to which languages are being taught. Results show that there is something of a disconnection between the languages provided and the languages that tourists desire in terms of their mother tongue. Those tourists who can speak English or Chinese may receive service support in those languages, while those who cannot may be disappointed.
