The ASEAN Inter-Parliamentary Assembly (AIPA) is a regional parliamentary body which acts as a primary point for communication and information sharing between member countries.

Its primary objectives are to provide information to Southeast Asian citizens about policies aimed at establishing an ASEAN community by 2025 and to foster mutual understanding and collaboration among these parliaments.

[5] In 1977, a decade after the founding of the Association of Southeast Asian Nations (ASEAN), the need to strengthen regional solidarity became increasingly apparent.

Legislators recognized that the growth of ASEAN was closely tied to the cooperation between the parliaments of its member countries, which represent the will and aspirations of the people.

Then, Indonesia's parliament speaker, Agung Laksono, said that the transition from AIPO to AIPA was not simply a change of words, but had profound meaning, expressing the aspirations of ASEAN peoples for the bloc's parliamentary organization to operate more effectively, towards a model of effective inter-parliamentary cooperation and closer cooperation between ASEAN parliaments.

Regarding the internal affairs of the parliaments of ASEAN member countries, the council only has advisory rights and lacks legislative and supervisory powers.

The AIPA General Assembly consists of delegations from each member parliament (not exceeding 15 people), and may invite additional special-observers, observers, and guests.

Normally, the term of office of the AIPA President is one year, equivalent to the time between two General Assembly sessions, and of course, it is also held by member countries in rotation.

[9] At each General Assembly, AIPA meets with dialogue partners such as Australia, Canada, China, Japan, South Korea, New Zealand, Papua New Guinea, Russia, India and the European Parliament.

[17] August 2023 marked the ASEAN Inter-Parliamentary Assembly's 44th General Session in Jakarta, which concluded with key document approvals and a handover of AIPA chairmanship.

[18] On September 16, 2024, the Serbian parliament formally requested an associate membership in the ASEAN Inter-Parliamentary Assembly (AIPA), citing historical cooperation in the Non-Aligned Movement.
