The Association of Southeast Asian Nations (ASEAN) is a regional grouping of all 11 states in Southeast Asia, which aims to promote economic and security cooperation among its members. Together, its member states represent a population of more than 600 million people and a land area of over 4.5 million km (1.7 million sq mi). The bloc generated a purchasing power parity (PPP) gross domestic product (GDP) of around US$10.2 trillion in 2022, constituting approximately 6.5% of global GDP (PPP). ASEAN member states include some of the fastest growing economies in the world, and the institution plays an integral role in East Asian regionalism.
The primary objectives of ASEAN, as stated by the association, are "to accelerate economic growth, social progress and cultural development in the region", and "to promote regional peace and stability through abiding respect for justice and the rule of law in the relationship among countries in the region and adherence to the principles of the United Nations Charter." In recent years, the bloc has broadened its objectives beyond economic and social spheres. The current Secretary-General is Kao Kim Hourn, while the chairmanship for this year is held by Malaysia, led by Prime Minister Anwar Ibrahim. The ASEAN chairmanship was handed over formally to the Philippines for 2026 on 28 October 2025. Full chairmanship will be assumed on 1 January 2026.
