Submissions to Y! for multiple countries

[karyno]

The answer to this question may be obvious to a lot of you but I need cold hard facts to present to my client.

My client is an Educational Institute and is currently breaking into the Australian and Chinese markets. If we do a submission to the Yahoo.com directory (US) is there much benefit in submitting to the other two and if so will we be required to pay for each one we submit to?
