5 June is Timor-Leste’s first National Day of the Sea!

A healthy ocean means a stronger, more resilient Timor-Leste, supporting livelihoods, creating jobs, protecting biodiversity and ensuring long-term prosperity for generations of Timorese to come.

The Blue Economy is not just an idea. It is a pathway to a sustainable future for Timor-Leste.

Join us on 5 June to celebrate Timor-Leste’s first-ever National Day of the Sea. Together, let’s us protect the sea that sustains us.

Timor is TASI!

TASI meaning sea in Tetum, is also an acronym for Timor, Azul, Sustentável no Inovador, a vision of Timor-Leste as a Blue, Sustainable and Innovative nation.

Our sea holds immense potential to improve the lives of our people through sustainable tourism, fisheries, aquaculture, salt production, seafood industries, and many other opportunities for future generations.

Join us on 5 June to celebrate the first-ever National Day of the Sea, to protect and sustain our beautiful seas for generations to come.

Timor-Leste and Indonesia have successfully concluded the third round of formal maritime boundary negotiations, held in Singapore from 27–29 April 2026. This round builds on significant progress made during the previous rounds in 2025 - held in Dili and Yogyakarta.

Timor-Leste’s delegation was led by Elizabeth Exposto, Chief of Staff to the Prime Minister Kay Rala Xanana Gusmão and Chief Executive Officer (CEO) of the Land and Maritime Boundary Office. The Indonesian delegation was led by His Excellency Ambassador Amrih Jinangkung, who is the Ambassador of Indonesia to the Netherlands and was the former Director-General for International Treaty Affairs in the Indonesia Ministry of Foreign Affairs.

The three-day meeting in Singapore saw constructive and sincere engagement, leading to meaningful progress being made. The two delegations worked diligently to foster mutual understanding and remained committed to working towards an equitable and acceptable solution for both two nations.

The fourth round of talks will be held in August in Indonesia.

Timor-Leste has previously concluded a permanent maritime boundary negotiation with Australia through a successful conciliation process under UNCLOS, resulting in a treaty between the two nations, signed in 2018 and ratified in 2019.
