Summary
The Association of Southeast Asian Nations: a regional organisation founded in 1967.
Today’s ASEAN members account for 8.5% of the world’s people (2025), 3.6% of the world’s GDP (2025), 2.3% of the world’s military spending (2025; 10 of 11 members have figures) and 5.5% of the world’s CO2 emissions (2024). Together they mine 74% of the world’s nickel, 15% of the world’s cobalt and 6.9% of the world’s rare earths (USGS, 2025, estimated). Of its members, 10 are also in RCEP, 7 in APEC, 2 in OPEC+ and 1 in BRICS.
Membership is as each grouping lists it. A grouping’s share of the world adds up its members’ figures, against the sum for every country with a figure.
