Country providing aid in trouble (5)
I believe the answer is:
'country' is the definition.
(India is an example)
'aid in trouble' is the wordplay.
'trouble' indicates an anagram.
'aidin' with letters rearranged gives 'INDIA'.
'providing' is the link.
(Other definitions for india that I've seen before include "where to ring for help?" , "Major sub-continent of Asia" , "The world's most populous democracy" , "Code for the letter I" , "Large subcontinent of Asia" .)
