With perhaps the exception of international finance the shipping industry is the world's most international business. The majority of ships are registered in countries like Liberia, Panama, the Bahamas; maritime labour comes from the Philippines, Bangladesh, and other low-cost countries. Container ships and oil tankers go between the world's biggest ports with little or no connection to their ‘home’ countries or ‘home’ shipowners. This has been the case for centuries. Another present feature is that much ownership and operation of the shipping tonnage are concentrated in small maritime countries, such as Greece, Denmark, and Norway. In these nations, the shipping industry does play an important role and the representatives of the industry, shipowners, politicians, and sailors organisations work to make the maritime sector visible and to stress its contribution to the nation's welfare, and not least national identity. As Anders Ravn Sørensen recent book Danmark som søfartsnation. Fortællinger, interesser og identitet gennem 250 år (Denmark as maritime nation. Narratives, interests and identity through 250 years) shows it takes some work.
