Oecusse
A piece of Timor-Leste on the north coast of West Timor, surrounded on land by Indonesia. It is where the Portuguese first landed on Timor, and it survived the Dutch–Portuguese carve-up of the island even though the Dutch wanted it gone. Today it is a special administrative region with its own economic zone.

Where Portuguese Timor began
Portuguese sailors and missionaries first landed on Timor at Lifau, near today’s main town of Pante Macassar, in 1515.[3] Oecusse-Ambeno was the first capital of Portuguese Timor, from 1701 to 1769, and it kept its ties to Portugal as the lands around it came under Dutch control.[1]
A treaty of 1859 split the island between Portugal in the east and the Netherlands in the west, and named Oecusse a Portuguese “enclave” in the Dutch half.[2] When the two agreed in 1893 to tidy up their lines, the Dutch argued that the deal meant the enclave should disappear. At a conference in The Hague in 1902 they dropped that claim, on condition that Portugal accept the Dutch line for Oecusse’s eastern border, and Portugal agreed rather than risk losing the whole territory.[2]
Surveyors fell out over where that line ran in 1909, and the two countries went to arbitration. On 25 June 1914 the arbitrator, C. E. Lardy, ruled for the Dutch line, with the Noèl Meto river as the border to the sea.[2]
Cut off
Oecusse’s separation from the rest of the country is why Timor-Leste’s 2002 constitution promised it special administrative and economic treatment. Since 1999 getting to the east has been hard: land and air links are few, and the boat service is erratic in some seasons and sometimes stops.[1]
In 2014 the enclave was made a Special Zone of Social Market Economy (ZEESM), and in January 2015 an unelected regional authority, led by former prime minister Mari Alkatiri, took over nearly all its government and budget.[1] He called it a “development laboratory” for the country, with its own investor-friendly laws; public money poured into roads, power and coastal projects in one of Timor-Leste’s poorest districts, where officials said more than 60 percent of people lived below the poverty line.[1]
In November 2015 the zone opened with a week of celebrations for the 500th anniversary of the Lifau landing. Some local people felt the event, run from Dili, was about Portugal rather than about Oecusse.[1]
