Tibet's neighbor (5)
I believe the answer is:
nepal
'tibet's neighbor' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nepal that I've seen before include "Asian country -- plane (anag)" , "somewhere in the Himalayas" , "Himalayan state" , "Himalayan country" , "hilly part of Asia" .)
