Singapore (Chinese: 新加坡; pinyin: Xīnjiāpō; Malay: Singapura; Tamil: சிங்கப்பூர்), officially the Republic of Singapore, is an island city-state located at the southern tip of the Malay Peninsula, lying 137 kilometers (85 mi) north of the equator, south of the Malaysian state of Johor and north of Indonesia's Riau Islands. At 710.2 km2 (274.2 sq mi), Singapore, a microstate and the smallest nation in Southeast Asia, is by orders of magnitude larger than Monaco and Vatican City. These, as well as San Marino, are the only other surviving sovereign city-states.
