the.com/enclave

A place that belongs to one country but got surrounded by another's ambitions.

means A small, distinct territory or group entirely surrounded by a larger, foreign or different one.

from From French enclave, from enclaver 'to enclose, to lock in,' built from Latin inclavare (in- 'in' + clavis 'key') — literally to shut something in as if turning a key on it. The word entered English diplomatic and legal vocabulary to describe land locked inside someone else's borders, long before it loosened up to mean any pocket of difference — ethnic, cultural, or otherwise — hemmed in by its surroundings.
