Concerning business in Asian river test? (10)

I believe the answer is:

industrial

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

'concerning business' is the definition.
'industrial' can be an answer for 'business' (thesaurus). I am unsure of the 'concerning' bit.

'asian river test?' is the wordplay.
'asian river' becomes 'indus' (I've seen this before).
'test?' becomes 'trial' ('trial' can be a synonym of 'test').
'indus'+'trial'='INDUSTRIAL'

'in' acts as a link.

Can you help me to learn more?

(Other definitions for industrial that I've seen before include "Characterised by manufacturing processes" , "Type of action" , "Like some business" , "Inlaid rust (anag.)" , "Relating to manufacture" .)

I've seen this clue in the Sydney Morning Herald.
