Generally speaking, the areas surrounding the Pacific Ocean are blessed with forest resources. Forest types from frigid to tropical are found in the Pacific region. Therefore, there are many countries which are able to export lumber products. Not only in developing countries, which have not fully exploited their re sources, but also in advanced countries mass production and export of lumber is occurring. But such production and export in advanced countries of the area is centered in the underdeveloped regions of those countries. For example, in cluded in such areas are the far eastern regions of the U.S.S.R. and the west coast of Canada and the U.S.A. (including Alaska). Exports from advanced countries consist mainly of softwoods and, from developing countries, of tropical hardwoods. There are many problems related to the rapid development of forest resources of each region when accompanying general economic growth, but in this paper I wish to limit consideration mainly to several points, focussing on the countries of Southeast Asia.
