Singapore is an island city-state in Southeast Asia, situated on the southern tip of Malay Peninsula, south of the state of Johor of Peninsular Malaysia and north of the Indonesian islands of Riau. The city has traded in its rough-and-ready opium dens and pearl luggers for towers of concrete and glass, and its steamy rickshaw image for hi-tech wizardry. Malaysia is physically split between west and east, parts united into one country in 1963. Western Malaysia is on the southern tip of the Malay peninsula, and stretches from the Thai border to the island of Singapore. Eastern Malaysia includes the territories of Sabah and Sarawak on the north end of Borneo, separated by the country of Brunei.
