unconcern

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

'indifference' is the definition.
('unconcern' can be a synonym of 'indifference')

'company led by international organisation' is the wordplay.
'company' becomes 'concern' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'led by' says to put letters next to each other.
'international organisation' becomes 'un'.
'concern' put after 'un' is 'UNCONCERN'.

'of' acts as a link.

Can you help me to learn more?

(Other definitions for unconcern that I've seen before include "Lack of interest" , "Apathy" , "Indifference" , "Calm" .)

I've seen this clue in The Guardian.
