Timor-Leste’s ASEAN accession opens a new stage of regional work
The country joined the Southeast Asian grouping as its 11th member in October 2025.
Timor-Leste became ASEAN's 11th member at the bloc's October 2025 summit in Kuala Lumpur. ASEAN had agreed in principle to admit the country in 2022 and adopted a roadmap for full membership the following year.
Formal membership gives the country a seat in the region's standing institutions. Work on applying the bloc's agreements continues after admission. For a small country, that means taking part in regional decisions while adapting domestic institutions to a larger set of commitments.
