--International Relations and National Security. Science and technology are becoming increasingly important elements of our national security and foreign policies. This is especially so in the current age of sophisticated defense systems and of growing dependence among all countries on modern technology for all aspects of their economic strength. For these reasons, scientific and technological considerations have been integral elements of the Administration's decision-making on such national security and foreign policy issues as the modernization of our strategic weaponry, arms control, technology transfer, the growing bilateral relationship with China, and our relations with the developing world. Four themes have shaped U.S. policy in international scientific and technological cooperation: pursuit of new international initiatives to advance our own research and development objectives; development and strengthening of scientific exchange to bridge politically ideological, and cultural divisions between this country and other countries; formulation of programs and institutional relations to help developing countries use science and technology beneficially; and cooperation with other nations to manage technologies with local impact. At my direction, my Science and Technology Adviser has actively pursued international programs in support of these four themes. We have given special attention to scientific and technical relations with China, to new forms of scientific and technical cooperation with Japan, to cooperation with Mexico, other Latin American and Caribbean countries and several states in Black America, and to the proposed Institute for Scientific and Technological Cooperation. In particular our cooperation with developing countries reflects the importance that each of them has placed on the relationship between economic growth and scientific and technological capability. It also reflects their view that the great strength of the U.S. in science and technology makes close relations with the U.S. technical community an especially productive means of enhancing this capability. Scientific and technological assistance is a key linkage between the U.S. and the developing world, a linkage that has been under-utilized in the past and one which we must continue to work to strengthen. --Space Policy. The Administration has established a framework for a strong and evolving space program for the 1980's.
