PPC for a high traffic non-English website?

I have a Korean website which has about 450,000 visitors a month.
I got banned from Adsense for invalid clicks(I guess) yesterday.
My monthly earning with Adsense was about $5000.
I want to keep making money with my website.
Do you know any good PPC program for a non-English website other than Adsense?
