The Portuguese established outposts in Timor and Maluku. Effective European occupation of a small part of present-day East Timor began in 1769 when the city of Dili was founded and the colony of Portuguese Timor declared. A definitive border between the Dutch-colonised western half of the island and the Portuguese-colonised eastern half was established by the Permanent Court of Arbitration of 1914, and it remains the international boundary between the successor states Indonesia and East Timor, respectively. For the Portuguese, East Timor remained little more than a neglected trading post until the late nineteenth century, with minimal investment in infrastructure, health, and education. Sandalwood continued to be the main export crop with coffee exports becoming significant in the mid-nineteenth century.
