You can open a local bank account as a non-resident. Technically, it will be similar to a passbook savings account. It needs to be set up as dual currency USD and RMB, so it can receive an incoming USD wire. Then the account holder will need to go to bank with passbook and have them convert all or part of it to RMB at that day's prevailing rate. Two separate running balances will be kept, one for each currency. This is a standard product offering for most of the major players in local banking.

The "hidden charge" is in the conversion rate--the difference from the current official rate (which you never quite achieve even under the best of circumstances) is 6.81-6.7 = 0.11 or RMB 330, which is about $48. This is a bigger spread than you find at most banks. So, added to the sending fee, your total cost is about $74. However, if you had the ability to bank wire to a theoretical local account, you would still incur an intl wire fee of $40-50 along with a better conversion rate, but the savings over WU method for this amount would only be about $10-$15. Bank wiring is most cost effective when you deal with larger amounts...like $5000-$10000+...or if you have Premier status at your bank and can get free intl wire privileges.
