Double Landlocked Countries
"A country is "doubly landlocked" or "double-landlocked" when it is surrounded only by landlocked countries (requiring the crossing of at least two national borders to reach a coastline). There are two such countries:
Liechtenstein in Western Europe, surrounded by Austria and Switzerland.
Uzbekistan in Central Asia, surrounded by Afghanistan, Kazakhstan, Kyrgyzstan, Tajikistan, and Turkmenistan." -Wikipedia
