It is the world's largest island country, with more than seventeen thousand islands, and at 1,904,569 km2, the 14th largest by land area and the 7th largest in combined sea and land area.

Java, the world's most populous island, contains more than half of the country's population.
The sovereign state is a presidential, constitutional republic with an elected parliament. It has 34 provinces, of which five have special status. Jakarta, the country's capital, is the second most populous urban area in the world. The country shares land borders with Papua New Guinea, East Timor, and the eastern part of Malaysia. Other neighbouring countries include Singapore, Vietnam, the Philippines, Australia, Palau, and India's Andaman and Nicobar Islands. Despite its large population and densely populated regions, Indonesia has vast areas of wilderness that support a high level of biodiversity. The country has abundant natural resources like oil and natural gas, tin, copper and gold. Agriculture mainly produces rice, palm oil, tea, coffee, cacao, medicinal plants, spices and rubber. Indonesia's major trading partners are China, United States, Japan, Singapore and India.
East Timor or Timor-Leste (Tetum: Timór Lorosa'e), officially the Democratic Republic of Timor-Leste (República Democrática de Timor-Leste, Repúblika Demokrátika Timór-Leste), is a country in Maritime Southeast Asia. It comprises the eastern half of the island of Timor, the nearby islands of Atauro and Jaco, and Oecusse, an exclave on the northwestern side of the island surrounded by Indonesian West Timor. Australia is the country's southern neighbour, separated by the Timor Sea. The country's size is about 15,410 km (5,400 sq mi).
East Timor was colonised by Portugal in the 16th century, and was known as Portuguese Timor until 28 November 1975, when the Revolutionary Front for an Independent East Timor (Fretilin) declared the territory's independence. Nine days later, it was invaded and occupied by the Indonesian military, and was declared as the country's 27th province the following year. The Indonesian occupation of East Timor was characterised by a highly violent, decades-long conflict between separatist groups (especially Fretilin) and the Indonesian military.
