This Asian unfortunately envies mate (10)
I believe the answer is:
vietnamese
'this asian' is the definition.
(Vietnamese is an example)
'unfortunately envies mate' is the wordplay.
'unfortunately' indicates anagramming the letters.
'envies'+'mate'='enviesmate'
'enviesmate' is an anagram of 'VIETNAMESE'.
(Other definitions for vietnamese that I've seen before include "People" , "Asian language" , "oriental language" , "Asians" , "Natives of Hanoi" .)
