CIL was delighted to host the book launch of Navigational Restrictions within the New LOS Context on 21 April 2017. The book manuscript was prepared in 1986 by Lewis M Alexander, a world-renowned marine geographer, as a report for the United States Department of Defense. Published by Brill, the book was edited by Captain J Ashley Roach, who faithfully reproduced its original structure and references. Section one of the book offers an exceptional primer on the 1982 United Nations Convention on the Law of the Sea. In addition, the book contains the compilation of geographic data—not available elsewhere—describing the world’s straits used for international navigation and illustrations of the chokepoints and major international shipping trade routes.
