Making money, as one can among the Chinese (7)
I believe the answer is:
minting
'making money' is the definition.
(I've seen this before)
'one can among the chinese' is the wordplay.
'one can' becomes 'tin' (both are metal containers).
'among' indicates putting letters inside.
'the chinese' becomes 'ming' (Chinese dynasty).
'tin' inserted inside 'ming' is 'MINTING'.
'as' is the link.
(Other definitions for minting that I've seen before include "Making coins" , "Making money" .)
