Unsettled, since he is from a far country (7)
I believe the answer is:
chinese
'from a far country' is the definition.
'unsettled since he' is the wordplay.
'unsettled' is an anagram indicator.
'since'+'he'='sincehe'
'sincehe' with letters rearranged gives 'CHINESE'.
'is' acts as a link.
(Other definitions for chinese that I've seen before include "Foreign" , "From Shanghai, say?" , "Of the most populous country" , "Oriental language" , "Since he, strangely, is this nationality" .)
