I may represent this country (5)
I believe the answer is:
india
'i' is the definition.
(India is I in the NATO phonetic alphabet)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for india that I've seen before include "Code for the letter I" , "Comms code for I" , "(Part of) subcontinent" , "It was once known as the Jewel in the Crown" , "Place of Kipling's birth" .)
