A landlocked country or landlocked state is a sovereign state that does not have territory connected to an ocean or whose coastlines lie on endorheic basins. Kazakhstan is the world's largest landlocked country . Countries that are landlocked by a single country are known as enclave countries . Example: Lesotho which is surrounded by South Africa, San Marino, a state surrounded by Italy, and Vatican City which is a city-state surrounded by Rome, Italy . A country is doubly landlocked or double-landlocked when it is surrounded entirely by one or more landlocked countries. There are two such countries: Liechtenstein in Central Europe, surrounded by Switzerland and Austria. And Uzbekistan in Central Asia, surrounded by Afghanistan, Kazakhstan, Kyrgyzstan, Tajikistan, and Turkmenistan.
