At a ceremony in Singapore on 31 August 2015, representatives of the International Tribunal for the Law of the Sea (ITLOS) and the Singaporean Ministry of Law signed a Joint Declaration for Singapore to provide facilities to ITLOS whenever it is desirable for ITLOS or a special chamber of ITLOS to exercise its functions in Singapore. ITLOS announced the arrangements in a joint press release, available here.
Established by the United Nations Convention on the Law of the Sea (UNCLOS or the Convention) in 1982, ITLOS sits to hear any dispute concerning the interpretation or application of the Convention. Currently, there are 167 parties to the Convention, which comprises 166 States and the European Union. Importantly, the United States has not signed or ratified the UNCLOS. Since it was founded in 1996, ITLOS has heard 24 cases (only five of which have been on the merits).
