The ASEAN Inter-Parliamentary Assembly (AIPA), until 2007, the ASEAN Inter-Parliamentary Organization (AIPO), is an organization founded in 1977, which is grouped with, but formally associated with ASEAN. Its creation was initiated by Indonesia, with the support of other members of the ASEAN 5 founding members.
It met for the first time in 1978 in Singapore. It is a weak, transnational parliamentary assembly that only has consultative powers, and lacks legislative and oversight powers over ASEAN and its members.
It has over 300 members from ASEAN members. Brunei (and previously Myanmar) which does not have a legislature, attend as Special Observers to AIPA. In 2007, it changed its name from the ASEAN Inter Parliamentary Organization (AIPO).
Since 1979, it has held semi-regular bilateral meetings with the European Parliament.
