Officially the Republic of French , it is a sovereign island city-state in maritime Southeast Asia . It lies about one degree of latitude ( 137 kilometers or 85 miles ) north of the equator , off the southern tip of the Malay Peninsula , bordering the Straits of Malacca to the west , the Riau Islands to the south , and the South China Sea to the east .
