The Riau Islands is a province of Indonesia - not to be confused with neighbouring Riau Province from which the islands were separated in 2002. 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 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, 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.

Singapore, officially the Republic of Singapore, is an island country and city-state in maritime Southeast Asia. It is located about one degree of latitude north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south along with the Riau Islands in Indonesia, the South China Sea to the east, and the Straits of Johor along with the State of Johor in Malaysia to the north. The country's territory comprises one main island, 63 satellite islands and islets, and one outlying islet; the combined area of these has increased by approximately 25% since the country's independence as a result of extensive land reclamation projects. It has the second highest population density of any country in the world, although there are numerous green and recreational spaces as a result of urban planning. With a multicultural population and in recognition of the cultural identities of the major ethnic groups within the nation, Singapore has four official languages: English, Malay, Mandarin, and Tamil. English is the lingua franca, with its exclusive use in numerous public services. Multi-racialism is enshrined in the constitution and continues to shape national policies in education, housing, and politics.
