Ads not displayed in Asia

Ads not showing in Asia Marketplace, do I need separate campaigns?

[jemmpd]

When I set-up my current campaign in Overture, I chose to have my ads shown in Hong Kong, Japan, Korea and The United States, along with the appropriate language. I have a few questions that Overture's customer support can't seem to answer...so I'm going to the experts.
1. It appears that when searching from an Asian IP address, using an Asian default language, most of the ads aren't showing, and when they do, sometimes they're in English. If this is common, could someone please explain?
2. I was told by customer support that in order for my ads to be shown in these marketplaces/countries with the appropriate language, the campaigns would need to be set-up in that version of Overture (ie: Overture Japan). Is this true? Do I need separate campaigns for each country?
Thanks for your help.

RE point 2: yes you need to setup accounts with the separate overture divisions (i.e Overture Hong Kong, etc), as each division has different distribution networks and other little differences. I have experienced the same issue in the past.

Thanks for the comment.
So when I set up the account and I included these Asian countries in my preferences, what was this for? where are the ads showing?
