One's in Modi's country and elsewhere (9)
I believe the answer is:
indonesia
'country and elsewhere' is the definition.
I can't judge whether this definition defines the answer.
'one's in modi's' is the wordplay.
'in' indicates putting letters inside.
'modi' becomes 'india' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ones' going within 'india' is 'INDONESIA'.
Can you help me to learn more?
(Other definitions for indonesia that I've seen before include "An ionised country of South East Asia" , "Asian republic" , "I said none (anag) - country" , "SE Asian country" , "State" .)
