I've researched this option a bit and I would recommend HSBC or Citibank.

They are the biggest and at most times the 'more sophisticated' bank in Hong Kong. Mind you, if your desposits are below US$10-20K, there are far more options available.
You do want to check with them what their transfer charges are for 'transfers within HSBC's network' i.e. from HSBC US to HSBC Hong Kong.
Citibank is also decent but they tend to have exhorbitant prices and generally have a bad attitude (reflected in several people I know who have worked or continue working there) towards low value customers.
You also might want to look at American Express, if you have a good long standing Amex account.
