The United Nations Convention on the Law of the Sea multilateral diplomacy at work.

Author:Goettsche-Wanli, Gabriele

The year 2014 marks the twentieth anniversary of the entry into force of the 1982 United Nations Convention on the Law of the Sea (the "Convention"). (1) The Convention has been widely accepted.

That committee was transformed one year later into the Committee on the Peaceful Uses of the Seabed and the Ocean Floor beyond the Limits of National Jurisdiction (the "Seabed Committee").

In 1970, the General Assembly declared that the seabed and ocean floor, and the subsoil thereof, beyond the limits of national jurisdiction, as well as the resources of the area, are the common heritage of mankind.
