The city lies within what the government calls the "Northern Regional Development Corridor", which stretches along the coast from the Indonesia border to Baucau. Within this, it is part of the smaller "Dili-Tibar-Hera" area in which the government plans to develop the service sector. The city is also part of what is designated the central tourism zone. Sites related to important historical events are promoted, as well as eco-tourism. Whale watching is possible off the coast, and there are many scuba diving sites near the city. Some tourism and industrial complexes are being developed within the metropolitan area. Half of visitors arriving at Dili's airport come from three countries: Australia, Indonesia, and Portugal.  Near the beginning of UN rule, there were at least 9 hotels with 550 rooms. As of 2012, there were at least 14 hotels in the city. Most hotels are run by local companies, with few international chains present. Nightly rates are relatively high for the region, partially due to a lack of sufficient tourists to benefit from economies of scale.
