In several UNESCWA countries, Bahrain, Iraq, Jordan and United Arab Emirates total foreign trade is larger than GDP, indicating their dependence on engaging in international trade patterns. Inland freight transport tends to involve higher volumes in developed and/or large countries, where the dependence on international trade (which is mostly facilitated by maritime and/or air transport) is lower than that of the smaller and/or land and sea-locked countries. In terms of value (imports and exports), maritime transport has been by far the most important transport mode. In September 2010, freight with a worth of €128 billion was transported by sea, €57 billion by air and €43 billion by road.
