Mandarin Font/Typeface?

Help! Not sure if this is where to go, but I'll try.

I have a client that I am developing a brochure for. They require 2 versions, one to be used in the US, one to be used in China. They are going to have a translater covert the english version to Mandarin chinese, but what font/typeface do I use for this conversion?

The file is built in InDesign CS 5.5. Utlizies Myriad Pro family; (not sure if that's needed - No idea!) - any help/guidance would be gratefully appreciated! Thank you!
