first of all.. asian traffic doesn't belong at sedo, domainsponsor and other ppc places PERIOD
...it converts horribly and whatever traffic does get counted is a small fraction of the whatever actual number of visitors your domain/s are getting
problem with asian traffic is actually catching it in the first place, for example sedo and fabulous name servers are banned from CHINA so if you have them parked there your not even getting the actual amount of visitors that you should be... japanese and korean traffic is fine... domainsponsor, hitfarm, domainhop and so on dismiss asian traffic because it's CRAP, advertisers don't want anything to do with that part of the world i suppose
what i would suggest you do is the following..... get your own virtual dedicated server (about $50 per month or so most places.. you get your own partition, unlimited domain hosting, etc..) you will setup your own name servers, that way you will start catching all traffic... now here is how your gonna start profiting from the traffic using google adsense, they serve ad's in chinese, japanese and korean..
setup a nice little informational "mini site" ..put up google adsense ad's wisely, for example right on top of your page, 728x90 leaderboard is what i use.. it has worked best.... and for example put up some pics of britney spears or somebody else who is pretty popular with the asians.. DONT LINK TO ANY EXTERNAL WEB SITES.... just put up some news/headlines or whatever other info you want regarding the whatever subject you will be covering..... the trick is to get them to click on the google ad's, which are the only links on your page... works like a charm.... all fair and square'
good luck buddy
