Are academic ethics global or local?

This question is inspired by this recent answer that mentions that whether downloading articles from 'questionable' sites is legal (not ethical) may depend on local law. That is, law is local.

Are academic ethics global or local? Clearly, legal principles and conclusions vary from place to place, but does the same apply to academic ethics, or are academic ethics the same no matter where you go? That is, while there may be (and may continue to be) genuine debates on various ethical matters in academia, do these debates and disagreements apply fully to academics everywhere in the world, or are there "local" ethics?

At first, I figured that getting large numbers of people scattered throughout the world to agree on anything is so remotely implausible that there must be local ethics, but then I realized that I couldn't think of any rational set of circumstances where I would advise a colleague that they could solve their ethical issue not by changing their behavior, but by crossing a border, e.g.,

Dude, while fooing the bar does not violate any specific statute in the Civil or Criminal Codes of Florin, it is near-universially considered academically unethical here! Have you considered a transfer to our branch campus in Guilder? You can foo the bar all you like there - they even have a Department of Fooing the Bar and award annual scholarships for the most bars fooed that year. Just take care that Guilderian ethics requires that you disclose your blood type to research subjects before you ask them to fill out a survey - people who don't are not charged in court per se, but their names get published in Guilder's Most Annoying Unethical Jerkfaces Quarterly and are rarely, if ever, allowed to return to academia there.
