<Li> The Danube is an international waterway, and thus landlocked Austria, Hungary, Moldova, Serbia, and Slovakia have secure access to the Black Sea (the same access is given to inland parts of Germany and Croatia, though Germany and Croatia are not landlocked). However, oceangoing ships cannot use the Danube, so cargo must be transloaded anyway, and many overseas imports into Austria and Hungary use land transport from Atlantic and Mediterranean ports . A similar situation exists for the Rhine river where Switzerland has boat access, but not oceangoing ships . Luxembourg has such through the Moselle, but Liechtenstein has no boat access, even though it is located along the Rhine, as the Rhine is not navigable that far upstream . </Li> <Li> The Mekong is an international waterway so that landlocked Laos has access to the South China Sea (since Laos became independent from French Indochina).
