The Association of South East Asian Nations, or ASEAN, was established in 1967, with the signing of the Declaration of the Association of Southeast Asian Nations (Bangkok Declaration). Alongside the five original nations (Indonesia, Malaysia, the Philippines, Singapore, and Thailand) and followed by the accession of Brunei Darussalam, Vietnam, Laos, Myanmar, Cambodia and Timor-Leste, ASEAN is now composed of eleven member states. ASEAN, which declared the establishment of the ASEAN Community in 2015, has achieved steady economic development, and is now attracting attention as the growth center of the world.
