evidence: The dispute over Pedra Branca dates back to 1979, when Malaysia published a map indicating that the island was within the country's territorial waters. Pedra Branca is located near the eastern entrance of the Singapore Strait, about 44km east of mainland Singapore. In 2008, the International Court of Justice (ICJ) ruled that Pedra Branca belongs to Singapore while Middle Rocks belongs to Malaysia. It also ruled that South Ledge belongs to the state in the territorial waters of which it is located. [...] Singapore has said that it stands ready to "robustly defend" its sovereignty over Pedra Branca.
