Where do entities such as Warner Music Korea and Universal Music Korea fit into the "big company small company" discourse?

I'm just curious

they aren't known as the big3 the GP of sk knows the big 3 companies well

Interesting question because I think every worldwide label, be it Universal, Sony Music, Columbia, etc, have some representation is most music markets. Not sure, but I don't think they devote many resources or have much interest in Asian markets and such.
