The major international legal activity in the field of maritime transport in the first half of the 1970's was the negotiation and eventual adoption in 1974 under the auspices of the United Nations Conference on Trade and Development (U.N.C.T.A.D.) of the Convention on a Code of Conduct for Liner Conferences. The treaty-making conference itself, convened in Geneva, Switzerland, was attended by over eighty states members of U.N.C.T.A.D., including, of course, all the major trading nations, as well as by many observer delegations from U.N.C.T.A.D. member states, specialized agencies, and non-governmental and intergovernmental organizations.
