Jakarta –
Timor Leste has finally become part of ASEAN, marking a new chapter in a young nation’s long journey towards regional recognition. After waiting fourteen years since its official submission in 2011, the country that was born from a long struggle for independence will officially become the 11th member of ASEAN in October 2025.
This decision is not just a diplomatic event, but rather a symbol of the process of consolidating political and institutional identity that Timor Leste is undertaking in the midst of the complex geopolitical terrain of Southeast Asia.
The long process towards membership shows the unique dynamics of ASEAN as a consensus-based organization. There is no quick mechanism in the association that places the principles of non-intervention and prudence as a basis.

In this context, Timor Leste’s patience and diplomacy are important assets. Strong support from Malaysia as Chair of ASEAN this year also provides space, with Prime Minister Anwar Ibrahim emphasizing that joining Timor Leste will benefit the entire region.
The statement is not just a political gesture, but rather a recognition of the country’s capacity to contribute to regional balance for economic, social and cultural benefits.
On the domestic side, Timor Leste does not appear as a country that is sterile from challenges. Prior to its membership, this country was rocked by public protests regarding the policy of purchasing luxury vehicles for members of parliament.
The government responded quickly by canceling the plan, showing that civil society pressure still has some control over political policy.
Observers such as Michael Leach from Swinburne University consider this incident to be evidence of the vitality of democracy in Timor Leste, a democracy that, although young, shows healthier resilience than a number of its Southeast Asian neighbors.
After Dili, then Port Moresby
Timor Leste’s entry into ASEAN brings a new dimension to the regional structure. Based on a report from Tommy Walker on DW, this membership opens up access to the ASEAN market of more than six hundred million people and is an opportunity to expand trade and investment networks.
However, these benefits are not immediate. Timor Leste needs to strengthen its production capacity, improve infrastructure, and build a competitive legal and economic governance system to adapt to regional standards.
Economically, the country is still dependent on the oil and gas sector, with limited diversification. Therefore, integration into ASEAN also means demands for real structural reform.
Behind the economic dimension, there is a significant political meaning. Timor Leste is one of the few countries in the region that consistently maintains a democratic system.
Its presence can be a balance between ASEAN’s diverse political configurations, from democracy, monarchy, authoritarian, to hybrid systems. In this context, Timor Leste’s membership is not only a matter of geographical representation, but also an affirmation of political values ​​that enrich ASEAN’s normative orientation amidst increasingly polarized global dynamics.
Meanwhile, Papua New Guinea is starting to show interest in pursuing a similar path. At a foreign minister level meeting at a regional forum in Kuala Lumpur on 11 July 2025, Minister of Foreign Affairs Hon.
Justin Tkatchenko stated that Papua New Guinea wants to transform from Special Observer status to become a full member of ASEAN. The official statement noted that the country is aware of its strategic and economic potential for the region—stressing that Papua New Guinea’s inclusion would give ASEAN “an economic foothold in the Pacific” and open up new trade and investment opportunities, highlighting its abundant natural resources such as LNG and crude oil exports, as well as its 2.4 million km² exclusive economic zone and significant biodiversity.
Even though it has not submitted a formal application for full membership, Papua New Guinea has prepared a Cabinet Policy Submission as a future administrative step, and has opened full diplomatic missions in four ASEAN countries with plans to open a fifth mission in Thailand.
This shows seriousness in meeting ASEAN membership expectations and ongoing institutional preparations.
ASEAN and Pasifika
In a broader context, ASEAN’s expansion eastward – through the integration of Timor Leste and potentially Papua New Guinea – shows a change in the way this organization defines itself. ASEAN is no longer just a diplomatic forum consisting of core countries on the mainland and main islands of Southeast Asia.
It is now a more inclusive platform, accommodating countries with diverse historical backgrounds, economic capacities and political systems. The inclusion of Timor Leste and the Papua New Guinea plan confirms that the concept of Southeast Asia is not static, and can even continue to be expanded through continuous dialogue, diplomacy and institutional learning to the Pacific region.
However, this new membership also reminds of a challenge that has long haunted ASEAN, namely the development gap between members. For Timor Leste and even for Papua New Guinea in the future, becoming a member is not the end of the journey, but the beginning of a process of adaptation to complex regional mechanisms.
Bureaucratic readiness, fiscal capacity and representational capabilities in ASEAN forums will be a real test for the effectiveness of its participation. Papua New Guinea, while offering resources and a strategic position, must be balanced with institutional reform and economic diversification for membership plans to be not merely symbolic but substantive.
However, the story of Timor Leste and the aspirations of Papua New Guinea show that regional integration is not simply a matter of economic measures or regional security. It is also about diplomatic skills, political strength, and belief in the importance of regional togetherness.
In an increasingly competitive global landscape, small steps from Dili towards ASEAN or from Port Moresby towards similar aspirations, are a reflection of the courage to negotiate positions, build legitimacy and take part in the broader order. And from countries such as Timor Leste and Papua New Guinea, ASEAN is reminded that the spirit of community does not grow from strength alone, but from the desire to recognize each other and work together, something that was the initial goal of the formation of ASEAN.
