CHIANG MAI, Thailand -- An editorial in The Japan Times a few weeks ago focused on the Japanese government's efforts to increase the number of foreign students in Japan. No one would disagree with the government's dual aims of assisting in the development of human resources of poorer Asian countries and increasing the international community's understanding of Japan. However, there are three questions that merit examination:

* What geographic areas are given priority for cultural exchanges?

* How should the problem of Japan's prohibitive cost of living be addressed?
