Obstructive international organisation attended by soldier wearing flashy stuff (10)

I believe the answer is:

unobliging

'obstructive' is the definition.

'international organisation attended by soldier wearing flashy stuff' is the wordplay.
'international organisation' becomes 'uno'.
'attended by' says to put letters next to each other.
'soldier' becomes 'gi' (government issue or general issue).
'wearing' is an insertion indicator.
'flashy stuff' becomes 'bling' (informal term for jewellery).
'gi' inserted inside 'bling' is 'bliging'.
'uno'+'bliging'='UNOBLIGING'

I've seen this clue in The Guardian.
