No nudity in the Hong Kong version.
Four Asian women pull up in a van in a warehouse. They step out, take off their lab coats and are fully nude underneath as male workers watch. They then climb up a ladder to the next level where they're put to work packaging cocaine. We see breasts, bush and butts on all of them.
Most of the full fontal nudity is non-erotic. A slew of anonymous women having to work nude in the heroin plant to prevent theft of product.
Extensive nudity is in the movie in two scenes.
A woman walks into a massage parlor and takes off her clothes. You see her bare breasts for about a minute. Pubic shots, too. She then goes underneath a table with a man on top, suggesting oral sex.
Then there is a long section with many females that are fully nude at the plant.
