Sister cities of Singapore

Singapore (/ˈsɪŋəpɔər/ or /ˈsɪŋɡəpɔər/), officially the Republic of Singapore, is the world's only sovereign city-state that is also an island country. It is located in Southeast Asia, off the southern tip of the Malay Peninsula and 137 kilometres (85 mi) north of the equator. Made up of the lozenge-shaped main island (widely known as Singapore Island but also known as Pulau Ujong, its native Malay name) and over 60 much smaller islets, it is separated from Malaysia by the Straits of Johor to its north and from Indonesia's Riau Islands by the Singapore Strait to its south. The country is highly urbanised with very little primary rainforest remaining, although more land is being created for development through land reclamation.

Part of various local empires since being inhabited in the second century AD, modern Singapore was founded by Sir Stamford Raffles as a trading post of the East India Company in 1819 with the permission from the Johor Sultanate. The British obtained sovereignty over the island in 1824 and Singapore became one of the British Straits Settlements in 1826. Occupied by the Japanese during World War II, Singapore declared independence from the United Kingdom, uniting with other former British territories to form Malaysia in 1963, although it was separated from Malaysia two years later. Since then, it has had a massive increase in wealth, and is one of the Four Asian Tigers.

Singapore is the world's fourth-leading financial centre, and its port is one of the five busiest ports in the world. The economy depends heavily on exports and refining imported goods, especially in manufacturing, which constituted 26% of Singapore's GDP in 2005. In terms of purchasing power parity, Singapore has the third-highest per capita income in the world.

Singapore is a unitary multiparty parliamentary republic with a Westminster system of unicameral parliamentary government. The People's Action Party has won every election since self-government in 1959. Slightly over five million people live in Singapore, of which 2.91 million were born locally. The population is highly diverse; the majority are Chinese with almost 75% of the total population, while Malays and Indians forming significant minorities. Reflecting this diversity, the country has four official languages: English, Malay, Chinese, and Tamil. One of the five founding members of the Association of South East Asian Nations (ASEAN), the country is also the host of the APEC Secretariat, and a member of the East Asia Summit, the Non-Aligned Movement, and the Commonwealth.
