ASEAN: Southeast Asia's Economic Club

How the Association of Southeast Asian Nations grew from a political grouping into a major economic region, and how its economic community works.

The Association of Southeast Asian Nations, or ASEAN, was founded in 1967 in Bangkok by Indonesia, Malaysia, the Philippines, Singapore and Thailand. It grew to ten members with Brunei, Vietnam, Laos, Myanmar and Cambodia, and Timor-Leste became its eleventh member in 2025.

A diverse region

ASEAN brings together very different economies:

Singapore, one of the richest countries in the world per person.
Middle-income economies such as Malaysia, Thailand, Indonesia, Vietnam and the Philippines.
Lower-income economies such as Myanmar, Laos, Cambodia and Timor-Leste.

Together, ASEAN has nearly 700 million people and a combined economy among the largest in the world.

Economic integration

The ASEAN Free Trade Area, launched in 1992, cut tariffs among members to near zero for most goods.
The ASEAN Economic Community, launched in 2015, aims for freer flows of goods, services, investment and skilled labour.
ASEAN signed trade deals with China, Japan, Korea, India, Australia and New Zealand, and is the hub of RCEP, the world’s largest trade bloc by GDP.

The ASEAN way

ASEAN works by consensus and avoids interfering in members’ internal affairs. This keeps a diverse group together but can make decisions slow and limit action, for example on Myanmar’s crisis after 2021.

Why ASEAN matters

It is a major destination for foreign investment, especially as companies diversify beyond China.
It is a key part of global electronics and auto supply chains.
It is an important trading partner for India.

Limits

Integration remains incomplete: non-tariff barriers, differing regulations and limits on labour movement persist. Intra-ASEAN trade is a smaller share of total trade than intra-EU trade.

The car part's journey

A car assembled in Thailand uses a transmission from the Philippines, wiring from Vietnam and electronics from Malaysia. Low tariffs within ASEAN let these parts cross borders cheaply, making the region work like one production network.

Thinking ASEAN is like the European Union

ASEAN has no common currency, parliament or court with EU-style powers. It relies on consensus and looser cooperation.

Key takeaways

ASEAN was founded in 1967 and has eleven members after Timor-Leste joined in 2025.
It includes very rich, middle-income and lower-income economies.
A free trade area and an economic community deepen integration.
ASEAN works by consensus, which keeps unity but slows action.
