Basically it’s an independent enclave run by ethnic Armenians, it is landlocked in Azerbaijan according to internationally recogonised borders, but the Armenians occupy most of the land between it and them since the first war.
To make matters more complicated the little section in the bottom left of Armenia, is an independent enclave run by ethnic Azeris.
Interesting. I presume TFK is backing the Armenians in this one, except of course for a few contrarians who will argue to the death for Azerbaijani control over the region.
