The Riau Islands (Kepulauan Riau) is a province of Indonesia. The capital of the province is Tanjung Pinang and the largest city is Batam. It shares a maritime border with Riau and Jambi to the east, Bangka Belitung Islands to the south, Singapore to the northeast, Malaysia and West Kalimantan to the west, and Vietnam and Cambodia to the north. It also shares a maritime border with the municipality of Kalayaan in the province of Palawan of the Philippines to the east. It comprises a total of 1,796 islands scattered between Sumatra, Malay Peninsula, and Borneo including the Riau Archipelago. Situated on one of the world's busiest shipping lanes along the Malacca Strait and the Natuna Sea (South China Sea), the province shares water borders with neighboring countries such as Singapore, Malaysia, and Brunei. The Riau Islands also have relatively large potential mineral resources and energy, as well as marine resources. The Riau archipelago was once part of the Johor Sultanate, which was later partitioned between the Dutch East Indies and British Malaya after the Anglo-Dutch Treaty of 1824, in which the archipelago fell under Dutch influence. A Dutch protectorate, the Riau-Lingga Sultanate, was established in the region between 1824 and 1911 before being directly ruled by the Dutch East Indies. The archipelago became a part of Indonesia following the occupation of the Japanese Empire (1942–1945) and the Indonesian National Revolution (1945–1949). The Riau Islands separated from the province of Riau in September 2002, becoming Indonesia's third-youngest province. A free trade zone of the Indonesia–Malaysia–Singapore Growth Triangle, the Riau Islands has experienced rapid industrialisation since the 1970s. The Riau Islands is one of the country's most prosperous provinces, having a GDP per capita of () as of 2011, the fourth highest among all provinces in Indonesia after East Kalimantan, Jakarta and Riau. In addition, as of 2018, the Riau Islands has a Human Development Index of 0.
