The 1982 United Nations Convention on the Law of the Sea (UNCLOS or the Convention) is one of the most important accomplishments in the development of international law in the twentieth century. As a comprehensive compilation of the modern law of the sea, the UNCLOS not only codifies numerous customary rules of law of the sea, but also progressively develops the treaty rules of law of the sea. Especially the three bodies established by the UNCLOS, namely the International Seabed Authority (ISA), the International Tribunal for the Law of the Sea (ITLOS) and the Commission on the Limits of the Continental Shelf (CLCS), have played an important role in facilitating the implementation of the UNCLOS and promoting stability and development of the international marine order. As a member of the big family of the States Parties to the UNCLOS, China has been faithfully fulfilling the obligations of the UNCLOS, fully engaged in the work of the three bodies and actively contributing its solutions and wisdom. In the process of implementing the UNCLOS, China has formed its own practices and policies.
