The South East Asian Co-operation (SEACO) Foundation is a Bangladesh-based platform promoting closer economic, educational, technological and institutional cooperation among five OIC countries of South and Southeast Asia:

Bangladesh, Brunei Darussalam, Indonesia, Malaysia and Maldives.

SEACO is founded on a simple principle: meaningful economic integration among the 57 Member States of the Organisation of Islamic Cooperation (OIC) can be advanced progressively through stronger regional and subregional cooperation.

SEACO therefore seeks to serve as a catalyst and building block within a wider process of OIC economic integration.
