claim: Singapore Strait is a territory of Malaysia
evidence: A Cooperative Framework for Maintaining Safety in the Straits of Malacca and Singapore [...] The Straits of Malacca and Singapore are a 1,000-kilometer channel of water located between the Malay Peninsula and Singapore to the north, and Sumatra and other Indonesian islands to the south. Almost half of all global seaborne trade and roughly one third of the world’s crude oil passes through this route, making it one of the most important shipping lanes in the world. It is also a lifeline for Japan, with more than 80% of the country’s oil imports transported through the Straits. [...] The Malacca and Singapore Straits are within the territorial waters of Indonesia, Malaysia, and Singapore. As per the UN Convention on the Law of the Sea, which took effect in 1994, the Straits’ safety administration, including the maintenance of navigational aids, is the responsibility of these three countries. Because Singapore is home to a large number of trading companies, it enjoys the economic benefits of the Straits and has built and maintained lighthouses and buoys. Malaysia and Indonesia benefit far less, however, and are therefore shouldered with a relatively greater expense burden. Recognizing that Japan is a main stakeholder, The Nippon Foundation has taken on some of that burden and for more than 40 years has provided support for safe navigation and the protection of the marine environment.
