Impartial peacekeepers stationed around India (8)
I believe the answer is:
unbiased
'impartial' is the definition.
(similar in meaning)
'peacekeepers stationed around india' is the wordplay.
'peacekeepers' becomes 'UN' (United Nations, peacekeeping organisation).
'stationed' becomes 'based' ('base' can be a synonym of 'station').
'around' indicates putting letters inside.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'based' placed around 'i' is 'biased'.
'un'+'biased'='UNBIASED'
(Other definitions for unbiased that I've seen before include "Not favouring one side or the other" , "Impartial" , "fair" , "Not partial or prejudiced" , "Not prejudiced or partisan" .)
