Both are doubly landlocked — surrounded entirely by landlocked countries, requiring crossing two borders to reach open ocean.
Neighbors (all landlocked): Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Turkmenistan. Nearest sea: Aral Sea (endemic, shrinking) or Caspian Sea (via Turkmenistan/Kazakhstan).
Neighbors (both landlocked): Switzerland, Austria. Nearest sea: Mediterranean (via Italy/France) or North Sea (via Germany) — both two borders away.
Only two doubly landlocked countries exist. (Liechtenstein since 1938 when Austria annexed; Uzbekistan since 1991 independence.)
