Key Facts

Kalimantan Utara, commonly known as North Kalimantan, is a province of Indonesia located on the northern part of Borneo island. It was established in 2012, making it Indonesia's newest province, carved out of the eastern part of East Kalimantan province. Situated at the northernmost tip of Indonesian Borneo, Kalimantan Utara shares international borders with the Malaysian states of Sabah and Sarawak to the north, while being separated from the Philippines by the Sulu Sea to the northeast. The province covers approximately 72,275 square kilometers and has a population of around 700,000 people according to recent estimates. Kalimantan Utara is administratively divided into four regencies (Bulungan, Malinau, Nunukan, and Tana Tidung) and one city (Tarakan), with Tarakan serving as the provincial capital and main urban center. The province's economy is primarily driven by agriculture, mining, and forestry, with significant oil and gas reserves, particularly in the Tarakan Basin. Its strategic location near international borders makes it an important hub for cross-border trade and connectivity within the BIMP-EAGA growth area.
