1. Introduction: Why Space Matters in ASEAN

The Association of Southeast Asian Nations (ASEAN) is a unique system of regional integration, appropriately balancing engagement with flexibility, while maintaining core values and principles. The ASEAN is also unique in terms of space technology development and utilisation. From some of the world’s oldest space programs (Indonesia) to countries having very limited experience even in satellite data applications (e.g. Cambodia), from purely academic and commercial national efforts (Singapore) to strong government-controlled programs (e.g. Vietnam), ASEAN member countries cover the full spectrum of possible cases. The ASEAN is a fascinating laboratory of space development, with a history overflowing with valuable lessons to be followed by newcomers to the space field. This introductory chapter presents the history, nature and functioning of the ASEAN as a regional integration system, before explaining why the decision was taken to limit the scope of this volume to ASEAN member countries.
