Secure-sounding Asian (4)
I believe the answer is:
thai
'asian' is the definition.
(Thai is an example)
'secure-sounding' is the wordplay.
'secure' becomes 'tie' (tying is a kind of securing).
'sounding' shows a homophone (sound like).
'tie' is a homophone of 'THAI'.
(Other definitions for thai that I've seen before include "Sort of massage" , "Asian language" , "Citizen of the country once known as Siam" , "Morte d'16author" , "Person from Bangkok?" .)
