With the philosophy of One Vision, One Identity and One Community, the ASEAN Inter-Parliamentary Assembly or AIPA serves as the center of communication and exchange of information within the AIPA Member Parliaments. AIPA aims to encourage understanding, cooperation, and close relations among Member Parliaments, Observer Parliaments and other parliamentary organizations. Additionally, AIPA also plays instrumental role in familiarizing the peoples of Southeast Asia with policies aimed at accelerating the realization of an ASEAN Community in 2015.
