Government interference affected investment in Rio (15)

I believe the answer is:

interventionism

'government interference' is the definition.

'affected investment in rio' is the wordplay.
'affected' indicates anagramming the letters.
'investment'+'in'+'rio'='investmentinrio'
'investmentinrio' with letters rearranged gives 'INTERVENTIONISM'.

I've seen this clue in The Telegraph.
