Enlargement of ASEAN

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 the Bangkok Declaration in 1967. Since then, the ASEAN's membership has grown to ten with the accession of Cambodia in 1999.

Currently, two states are seeking accession to ASEAN: Papua New Guinea and East Timor.
