C is A's enclave and is B's exclave.

In human geography, an enclave is a piece of land which is totally enclosed within a foreign territory. If another country has sovereignty over it, it may also be called an exclave:

  • it is an enclave of the foreign territory which surrounds it
  • it is an exclave of the country which has sovereignty over it

Exclave may also exist in subnational level when a subdivision exists outside of its parent division. (See #Subnational examples)

The word 'enclave' crept into the jargon of diplomacy rather late in English, in 1868, coming from French, the lingua franca of diplomacy, with a sense inherited from late Latin inclavatus meaning 'shut in, locked up" (with a key, late Latin clavis). The 'exclave' is a logical extension created three decades later.

A coastal territory cannot correctly be called enclaves, since the sea is not a foreign territory, hence disqualifying it of the "enclosed on all sides by foreign territory" criteria.

Coastal countries

Countries that border just one country and the sea:
