Liberal France’s expression of agreement with troubled Asian state (9)
I believe the answer is:
louisiana
'state' is the definition.
(I know that Louisiana is a state)
'liberal france's expression of agreement with troubled asian' is the wordplay.
'liberal' becomes 'l' (abbreviation).
'france's expression of agreement' becomes 'oui' ('yes' in French).
'with' is a charade indicator (letters next to each other).
'troubled' indicates anagramming the letters.
'asian' is an anagram of 'siana'.
'l'+'oui'+'siana'='LOUISIANA'
(Other definitions for louisiana that I've seen before include "American state, capital Baton Rouge" , "IOU a snail over in the US state" , "US state, capital Baton Rouge" , "US southern state" , "that's near Mississippi" .)
