china sea

snake pit
I'm a little stuck... Click here to teach me more about this clue!

'asian region' is the definition.

'track round cool area in' is the wordplay.
'track' becomes 'chase' (synonyms).
'round' is an insertion indicator.
'cool' becomes 'in' ('in' can mean fashionable or cool).
'area in' becomes 'a' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'chase' going around 'in' is 'chinase'.
'chinase'+'a'='CHINA SEA'

Can you help me to learn more?

(Another definition for china sea that I've seen is " Pacific area".)
