Singapore is a hi-tech, wealthy city-state in south-east Asia, also known for the conservatism of its leaders and its strict social controls. The country comprises the main island - linked by a causeway and a bridge to the southern tip of Malaysia – and approximately 50 smaller islands. Once a colonial outpost of Britain, Singapore has become one of the world's most prosperous places - with glittering skyscrapers and a thriving port. Its strategic location, a skilled work force, pro-foreign investment and export-oriented, led to a successful free-market economy which attracts international investment funds on a large scale despite its relatively high-cost operating environment.
