Southeast Asia is composed of eleven sovereign states of impressive diversity in religion, arts, culture, politics and history. These are Brunei, Burma (Myanmar), Cambodia, Timor-Leste, Indonesia, Laos, Malaysia, the Philippines, Singapore, Thailand, and Vietnam. The region is also one of the fastest growing areas of the world economically, which largely accounts for its current international significance. Ten of these countries are members of ASEAN (Association of Southeast Asian Nations), with Timor-Leste as an observer. ASEAN is a political and economic organization aimed primarily at promoting economic growth and regional stability among its members.
