Declaration recognising the Right to a Flag of States having no Sea-coast
The Declaration recognising the Right to a Flag of States having no Sea-coast (French: Déclaration portant reconnaissance du droit au pavillon des États dépourvus de littoral) is a 1921 multilateral treaty which legally recognised that a land-locked state could be a maritime flag state; that is, that a land-locked state could register ships and sail them on the sea under its own flag. As of 2013, over 50 states have ratified the Declaration, and international law recognises the right of any state to sail ships on the sea under its own flag.
