Nation appears in Kremlin dialogue (5)
I believe the answer is:
india
'nation' is the definition.
(India is an example)
'in kremlin dialogue' is the wordplay.
'in' says the answer is hidden in the clue.
'INDIA' is hidden in the letters of 'kremlin dialogue'.
'appears' is the link.
(Other definitions for india that I've seen before include "Country of the Ganges" , "Country: I (comms.)" , "Comms code for I" , "Commonwealth country, independent in 1947" , "Bollywood's country" .)
