Landlocked country: definition, characteristics, examples, and implications

Characteristics and types

Being landlocked affects geography and practical access. A landlocked state may still border an enclosed or saline basin that itself has no ocean outlet. Such basins are called endorheic and the largest example is the Caspian Sea, which is not connected to the world ocean. By contrast, bodies like the Gulf of Mexico are open to wider ocean systems and do not make adjacent states landlocked.

Historical causes and development

States become landlocked for several reasons: continental interior location, the drawing of borders during decolonization, and results of wars or treaties that moved or removed a coastline. Historic conflicts and diplomatic settlements have left some countries without seaports, a condition that can persist for generations. Nations respond by negotiating transit and port access arrangements with neighbors, building rail links, and developing river corridors.

Examples

• Armenia
• Austria
• Luxembourg
• Chad
• Liechtenstein — one of the two fully recognized doubly landlocked countries
• Uzbekistan — the other fully recognized doubly landlocked country

Economic and political implications

Landlocked states generally face higher transport costs because international trade requires crossing one or more neighboring territories to reach seaports. To reduce friction they rely heavily on negotiated transit agreements, regional economic corridors, inland logistics hubs and multimodal links (road, rail, river and air). Access to neighbors’ ports, preferential customs treatment and stable diplomatic relations are often central to a landlocked country's development strategy.

Notable distinctions and facts

Some coastal basins are themselves effectively landlocked; the Caspian Sea is the best-known example. When discussing landlockedness it is important to separate political recognition and geography: a territory can be geographically surrounded by other landlocked countries and therefore be "doubly landlocked." International law and regional agreements play a key role in guaranteeing freedom of transit and in creating practical solutions that allow landlocked states to participate in maritime trade despite their lack of direct ocean frontage.
