This could be achieved through allowing corporations that are in marine transportation, air transportation, rail road companies, road authorities, storage facility companies and ports/air port authorities to raise money through capital markets in countries of the Area, especially countries that are capital surplus ones.
The Area can draw on the experience of the UAE in this respect, when it allowed its banking system to raise money for Indian companies as early as the eighties of last century. Certain Indian companies were allowed to raise capital against certain commitments and undertakings.
