Eastern relation on the move (8)
I believe the answer is:
oriental
'eastern' is the definition.
(similar in meaning)
'relation on the move' is the wordplay.
'on the move' is an anagram indicator.
'relation' with letters rearranged gives 'ORIENTAL'.
(Other definitions for oriental that I've seen before include "Non-European" , "from Japan, say" , "Relation of Eastern origin" , "Maybe Chinese" , "Eastern {8}" .)
