Wired transfer is the fastest way, only 2 business days to most banks in China. There is a base fee, about $40, then a percentage of the amount being tranferred. In my own case, I paid $50 on $20,000 wired transfer at Bank of Montreal.
You'll need:
-bank routing number (branch number plus bank number)
-account number
-name of the receiving bank
-address of the receiving bank
-home address of the recipient
-telephone number of the recipient
Normally you should go to your own bank to wire transfer, however if you choose to go to other banks, make sure to carry either a certified cheque or a band draft, so that the fund can be cleared right away.
