Am a fan of public nudity, esp those very ingenious shots by Spencer Tunick!
There's no doubt all peoples/races of the world have taken part in them, may it be Africans, Asian (Japanese, Indian, Chinese, even Pakistanis), Arabs, euh... and the ever-present 'whites'.
Here's one High Quality shot taken in Salford, Manchester, UK May 2010.
Just have a look
who's standing right behind THE man himself 
Btw, his Sydney shots attracted a noticeable number of Asian chicks (I haven't calculated these based on the pics littering the Net, but one of the folks in my firm's Sydney office - who took part that day - witnessed an unusually high number of Asian ladies from their early 20s to late 50s disrobing for the shoot that day - great for us!)
