Timor-Leste is an island nation in Southeast Asia. In 2002, Timor-Leste became an independent nation and the 191st member of the United Nations.

Establishing permanent maritime boundaries is a national priority for Timor-Leste.

In 2015, the Government of the Democratic Republic of Timor-Leste established the Council for the Final Delimitation of Maritime Boundaries which had the principal purpose of achieving permanent maritime boundaries for the nation.

In this context, and after a long process to delimit permanent maritime boundaries with Australia, Timor-Leste initiated the compulsory conciliation mechanism under the aegis of the United Nations Convention on the Law of the Sea (UNCLOS) to establish permanent maritime boundaries with Australia.

On August 30, 2018, and following this process, the “Treaty between the Democratic Republic of Timor-Leste and Australia establishing their respective maritime boundaries in the Timor Sea” entered into force.

However, in order to achieve full sovereignty, Timor-Leste still has to finalize its land and sea boundaries with Indonesia.

In December 2023, the Land and Maritime Boundaries Office was created, replacing the Council for the Final Delimitation of Maritime Boundaries, to define the necessary conditions and objectives leading to the signing of treaties establishing the respective land and maritime boundaries with the Republic of Indonesia. The specific competencies of the Land and Maritime Boundaries Office were also extended to support the Prime Minister in carrying out his duties relating to the Blue Economy.
