The most recent addition to the list of landlocked countries was Serbia, which formerly had access to the Adriatic Sea but when Montenegro became an independent country in 2006, Serbia lost its ocean access.
Doubly-Landlocked Countries
There are two special landlocked countries that are known as doubly-landlocked countries, completely surrounded by other landlocked countries. The two doubly-landlocked countries are Uzbekistan (surrounded by Afghanistan, Kazakhstan, Kyrgyzstan, Tajikistan, and, Turkmenistan) and Liechtenstein (surrounded by Austria and Switzerland).
