Oriental perhaps like a Scotsman? (5)
I believe the answer is:
asian
'oriental perhaps' is the definition.
(oriental is a kind of Asian)
'like a scotsman?' is the wordplay.
'like' becomes 'as'.
'a scotsman?' becomes 'ian' (I've seen this before).
'as'+'ian'='ASIAN'
(Other definitions for asian that I've seen before include "Continental native" , "Relating to one continent" , "One from the East" , "Eastern national" , "like the majority of people" .)
