Timor-Leste has officially become the 11th member of the Association of Southeast Asian Nations (ASEAN), ending a 14-year wait since first applying in 2011.
A viral video from the Kuala Lumpur Convention Centre, where the ASEAN Summit took place on Sunday (26 October 2025), showed delegates from Timor-Leste in tears as their national flag was raised beside those of other Southeast Asian countries.

Prime Minister Xanana Gusmão was visibly moved during the ceremony. “This is not just a dream come true, but also a powerful affirmation of our journey marked by resilience, determination, and hope,” he said, quoted by AFP.
“This is not the end of our journey. It’s the beginning of an inspiring new chapter.”
President José Ramos-Horta had earlier described the accession process as challenging. During a visit to the ASEAN Secretariat in Jakarta in August 2025, he said joining ASEAN was “harder than entering heaven” because of the extensive conditions that had to be met.
Long Road to Membership
Timor-Leste, formerly known as East Timor, gained independence in 2002 and applied for ASEAN membership in 2011.
The nation hoped to join by 2015, as stated in its Strategic Development Plan, but the process stalled for years due to concerns about its economic readiness and administrative capacity.
Under the ASEAN Charter, a country seeking membership must:
- Be located in Southeast Asia;
- Be recognised as a sovereign state by existing members;
- Agree to and comply with the ASEAN Charter; and
- Demonstrate the ability and willingness to meet all membership obligations.
These obligations include opening embassies in every member state, attending all ministerial meetings and summits, and acceding to ASEAN treaties and agreements.
An ASEAN feasibility study in 2016 concluded that Timor-Leste still lacked sufficient human resources and economic strength to meet all requirements.
Several members, including Singapore and Laos, expressed reservations that the country’s limited economic capacity, with its gross domestic product standing at around US $1.44 billion, might strain the organisation.
Despite these concerns, Timor-Leste continued to pursue reforms. The country established embassies in all ASEAN states by 2015 and opened an ASEAN secretariat in Dili. It also hosted the ASEAN People’s Forum in 2016 and participated in regional discussions as an observer.
In 2022, ASEAN granted Timor-Leste observer status, allowing its officials to attend all summits. Support for full membership grew gradually, led by the Philippines in 2015 and later by Indonesia, Thailand, Cambodia, and Malaysia.
By September 2025, the process neared completion as senior officials met in Port Dickson, Malaysia, to finalise preparations for Timor-Leste’s full accession.
