One of the world’s poorest nations, questions have inevitably been raised about the ability of Timor-Leste to contribute significantly to ASEAN's development agenda. The country’s economy remains dependent on oil and gas resources with minimal diversification into other industries, and it struggles with high levels of unemployment, inequality, and malnourishment. It also has issues with human resource capability and infrastructural development, which are thought to be essential for successful engagement in the ASEAN economic community.
However, Timor-Leste will have access to ASEAN's sizable export market and more job possibilities as a result of achieving full membership. This opens the prospect to draw both domestic and foreign investments with a more predictable investment regime, gaining support for structural reforms and modernisation efforts. Joining ASEAN may also contribute to the transformation of Timor-Leste’s public administration.
Notwithstanding a clear roadmap, there are still worries that Timor-Leste's admission would impede the development of the ASEAN Economic Community and that the nation's ambiguous geopolitical position might affect ASEAN's consensus-based decision-making process. The region is grappling with the US-China rivalry, with the economic dimension made acute by US President Donald Trump’s tariff agenda. In 2023, Timor-Leste and China formed a Comprehensive Strategic Partnership, and Ramos-Horta last year speculated about involving Beijing further in the country’s development needs should partnerships with neighbouring Australia not be fulfilled.
Anwar, however, also sees Timor-Leste’s admission to ASEAN as a means of strengthening ties between the Southeast Asian grouping and the Pacific Islands Forum, which is also receiving increased attention from China. Timor-Leste enjoys cultural ties to the Pacific and is also located alongside key trading routes.
The inclusion of Timor-Leste as a full member of ASEAN would also enhance ASEAN’s global standing. By supporting a small, post-conflict democratic nation, the bloc burnishes its image as a promoter of stability, democracy and development – the foundational principles on which ASEAN was based. It is anticipated that ASEAN membership will create further educational and capacity-building possibilities for Timorese. It also gives the region a basis for cooperation on increased market access, improved connectivity, and streamlined trade, all while contributing to global norms and standards.
