MaJunior's comment left a sticky in my head, and Emberskyes' point about an older city resonated as well. May I propose -
Hong Kong!
There's well established lore on it (it's got its own excellent book from years ago).
Key features to consider for chargen:
- there's no prince at this point, only primogen
- it's cosmopolitan enough to encompass characters of any descent, you don't have to make an asian character. The former prince certainly wasn't.
- your sires will have lived through the British handover to China
- or your sires might have moved to HK to get away from the major vampire political conflicts in US and Europe (5e advances the plot for the Camarilla Anarch conflicts, the slight retreat of the Sabbat, and the rise of the Second Inquisition) and living in a place without a prince allows for that, also explains why they were allow to sire.
- in lore terms, something may have happened between Kindred and kuei-jin in the recent past, but we're not delving into that
You can choose to ignore some of the bullets above of course, and just let things play out. I will be happy to describe things as they unfold. So your character can still make sense as you create it without worrying too much about history.
