Killing juvenile Chinese may be reported (10)

I believe the answer is:

euthanasia

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

'killing' is the definition.
(euthanasia is a kind of killing)

'juvenile chinese may be reported' is the wordplay.
I cannot quite see how this works, but
'chinese' could be 'han' (Chinese dynasty) and 'han' is present in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for euthanasia that I've seen before include "Mercy killing" , "Painless method of killing" .)

I've seen this clue in The Guardian.
