Theres also a context of western brands being foreign, so they will often use european faces in their ads, either alone or in mixture with asian faces. And this is expected. The foreign face is seen as part of the foreign brand.
If they use an asian face which they normally do these days, usually there is no issue, but it is not unheard of for the situation the thread is about to occur, or the Dolce and Gabanna ad type of controversy.
The reverse isnt true. Unless it is distinctively a cultural product, Asian companies in the west often downplay their asianess. So there is still a unequal relationship between east and west in that respect. Though this is starting to change more and more with respect to cultural mass media, IPs, and a broader range of consumer goods.
