Vessel in China or Taiwan (5)

I believe the answer is:

aorta

'vessel' is the definition.
(aorta is a kind of vessel)

'in china or taiwan' is the wordplay.
'in' says the answer is hidden in the clue.
'AORTA' is hidden within 'china or taiwan'.

(Other definitions for aorta that I've seen before include "vital transporter" , "Main artery of body" , "Heart's great artery" , "Large artery of the heart" , "Main arterial vessel, carrying blood to the heart" .)

I've seen this clue in The Times.
