Embargoed country (4)
I believe the answer is:
cuba
'embargoed country' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cuba that I've seen before include "Island country involved in a 1962 missile crisis" , "Island N. of Jamaica" , "Island S. of Florida" , "neighbour to America" , "Its capital is Havana" .)
