동남아시아 국가 연합
The Enlargement of the Association of Southeast Asian Nations is the process of expanding the Association of Southeast Asian Nations (ASEAN) through the accession of new member states. This process began with ASEAN's five original members, who founded the association through the signing of Bangkok Declaration in 1967. Since then, the ASEAN's membership has grown to ten with the accession of Cambodia in 1999.
