⭐ Core Definition: Accession of Timor-Leste to ASEAN

Timor-Leste became a member state of the Association of Southeast Asian Nations on 26 October 2025 during the 47th ASEAN Summit, finishing a two-decade accession process.

The island nation was recognised as an observer to ASEAN soon after it gained independence in May 2002. By 2007, all of its political parties supported closer ties with the organisation, and leaders declared a "strategic decision" to seek membership. The country applied for membership in 2011, and ASEAN agreed in principle to admit the country and make it a formal observer in 2022.

👉 Accession of Timor-Leste to ASEAN in the context of Timor Leste

Timor-Leste, also known as East Timor, officially the Democratic Republic of Timor-Leste, is a country in Southeast Asia. It comprises the eastern half of the island of Timor, the coastal exclave of Oecusse in the island's northwest, and the islands of Atauro and Jaco, for a total land area of 14,950 square kilometres (5,770 sq mi). Timor-Leste shares a land border with Indonesia to the west; Australia is the country's southern neighbour, across the Timor Sea. Dili, on the north coast of Timor, is its capital and largest city.

Timor was settled over time by various Papuan and Austronesian peoples, which created a diverse mix of cultures and languages linked to Southeast Asia and Melanesia. East Timor came under Portuguese influence in the sixteenth century, remaining a Portuguese colony until 1975. Internal conflict preceded a unilateral declaration of independence and an Indonesian invasion and annexation. The subsequent Indonesian occupation was characterised by extreme abuses of human rights, including torture and massacres, a series of events named the East Timor genocide. Resistance continued throughout Indonesian rule and in 1999, a United Nations–sponsored act of self-determination led Indonesia to relinquish control of the territory. On 20 May 2002, Timor-Leste became the first new sovereign state of the 21st century. That same year, relations with Indonesia were established and normalised, with Indonesia also supporting Timor-Leste's accession into ASEAN.
