Singapore is a very small island nation with very large attractions and achievements. Strategically situated on the tip of the Malaysian peninsula between the Indian Ocean and the South China Sea, Singapore has made itself the busiest port in the world, the second largest oil refiner on the planet and a major international financial centre. While Singapore's astonishing wealth sets it apart from most tiny islands, it is its population that makes it unique. A melding of Chinese, Malay and Indian peoples, this Southeast Asian crossroads has become a model of ethnic and religious harmony. Singapore also stands out as the cleanest, most efficient, most highly organized society in Asia.
