LPGA to mandate Koreans and others speak English

The LPGA Tour is going to force its burgeoning South Korean contingent of players to learn to speak English or risk losing their playing privileges.

Starting next year, the Tour announced that players who have been on the tour for two years must pass a oral English test or face suspension.
I understand there are a lot of Korean players in the tourney, but what gives? I can't think of a single reason how this would improve the sport...

I thought about posting this in PPB but I figured this is more of wacky/dumb sports news than a public policy topic.
