"More than 80% of international trade in goods is carried by sea, and an even higher percentage of developing-country trade is carried in ships.The Review of Maritime Transport, an annual publication prepared by the Division on Technology and Logistics - UNCTAD secretariat, is an important source of information on this vital sector. It closely monitors developments affecting world seaborne trade, freight rates, ports, surface transport, and logistics services, as well as trends in ship ownership." (Quoted from paper)
