International ocean shipping
constitutes a highly significant aspect of world economic and political
relationships. The rapid growth in world trade and the emergence of new national
entities in the last 30 years have further emphasized the role of international
shipping. Because of the generally free environment in which it has operated,
the industry is highly mobile and flexible—characteristics that, together with
technological progress, have facilitated the rapid growth in world
trade. In recent years, however, there have been several technological and institutional developments that are likely to have major efforts on the industry. One of the latter is the aggregation of conventions and practices known as the Law of the Sea, which has been discussed in the United Nations Conference on the Law of the Sea since 1958.
