- Our Boundaries
Timor-Leste and Indonesia share the island of Timor. The western boundary between the countries is 125 km in length with Indonesia to the west and Timor-Leste to the east as well as the enclave of Oe-Cusse.
In the 16th century Timor was colonised by the Portuguese and the Dutch who fought for control of the island. The first boundary delimitation occurred in 1859, followed by several agreements and concluding as a final delimitation in 1904. Indonesia became independent in 1945 while Timor-Leste unliterally declared independence in 1975, which was later restored in 2002 after a period of occupation followed by United Nations administration.
Timor-Leste and Indonesia have been negotiating the finalisation of their land boundaries for many years and this process is almost completed. The areas that remain subject to negotiations are less than two percent of the land boundary. The final segments have complex characteristics or features that require further detailed discussions to resolve, for example in Noel Besi/Citrana, Oe-Cusse which requires agreement on the exact terminus points where the land boundary meets the sea H.E. Kay Rala Xanana Gusmao is leading this negotiation pursuant to Government Resolution No. 22/2018 of 5 December.
