Please see Pam Spaulding's smackdown of a Burger King ad that ran in Singapore, with a "seven incher" headed to the open-mouth of a pornified woman. The link includes where to write to complain.
I've seen this phenomenon in other countries, where U.S. companies feel free to run much more sexist ads than they would here.

It may be more acceptable to have a Western-looking woman in the ad because of the stereotype that we're less moral. Of course, whites have a litany of Othered women who they consider less moral. Each society seems to have its own ideas about outsider men who are sexy (or scary) studs and outsider women who are just asking for it. Here's an unscientific sampling from Yahoo.
