The Declaration on the Admission of Timor-Leste was signed on 26 October 2025 at the 47th ASEAN Summit in Kuala Lumpur. East Timor became the bloc’s 11th member that day, the first new entrant in almost 25 years.
“This is a dream realised,” Prime Minister Xanana Gusmão told the other leaders. “It is not the end of our journey. It is the beginning of an inspiring new chapter.” President José Ramos-Horta, who lobbied for independence from exile, called membership “a strategic goal I spoke of in the 1970s, when we had nothing but conviction and hope.”
A long road to the table
Timor-Leste applied in 2011. The request sat for more than a decade. Singapore was among the members that wondered whether a young, oil-dependent state with a thin bureaucracy could carry the load of hosting hundreds of meetings and aligning on trade rules.
The turn came in 2022, when leaders meeting in Phnom Penh agreed in principle to admit it and gave it observer status. A year later a roadmap set out what Dili had to build, from ministries to conference facilities. Malaysian officials now say the country has met six of the seven readiness criteria in that roadmap. The one outstanding item is hosting capacity.
The country’s own history made the wait feel longer. It declared independence from Portugal in 1975 and was invaded by Indonesia days afterward. The resistance, led by Gusmão in the mountains and Ramos-Horta abroad, cost more than 100,000 lives by the account of one analysis. After a UN-supervised referendum in 1999, militias burned much of the territory. Independence was restored on 20 May 2002.
What membership is worth
Inside the bloc, Timor-Leste gets a market of about 650 million people and an economy of nearly US$4 trillion. It also gets a seat at meetings with China, Japan, India, the European Union, Australia and the Gulf states. ASEAN and its partners have started training Timorese civil servants in customs procedures, food safety and disaster response.
The home economy is the pressure point. About 1.4 million people live there, and it is the region’s poorest member. Public spending depends on the Bayu-Undan gas field, which is now depleted. The next hope, Greater Sunrise, is stuck in disputes with Australia over pipelines and profit-sharing. Without new income, the sovereign wealth fund could start shrinking within a decade.
India’s Prime Minister Narendra Modi was among the first to congratulate Dili and called the moment “historic and heart-warming.”
The admission was not unanimous in spirit. Myanmar’s junta reportedly tried to block it, accusing Dili of backing the National Unity Government that opposes military rule. ASEAN went ahead anyway.
One Timorese civil-society leader put the new workload this way: “It’s a bit like enrolling in a regional school. Now we have to do the homework.”
