Outsiders to keep ownership of Asian art? (4)

I believe the answer is:

kpop

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

'asian art?' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'outsiders to keep ownership' is the wordplay.
'outsiders to' suggests removing the centre (only letters on the outside of the word).
'ownership' becomes 'op' (I can't explain this - if you can you should believe this answer much more).
'keep' with its centre taken out is 'kp'.
'kp'+'op'='KPOP'

'of' is the link.

Can you help me to learn more?

I've seen this clue in The Irish Times.
