Can/ must a 2nd edition of a title carry a different ISBN number if now published under a different address from a different country?

From http://www.isbn.org/standards/home/isbn/international/html/usmfaq.htm :

Q: I am revising a book. Does it require a new ISBN?

A: A (substantial) change of text requires a new ISBN, and if revisions have been made the back of the title page should state that the book is a revised edition, and the new ISBN should be printed there.

And from http://www.isbn.org/standards/home/isbn/international/html/usm5.htm :

5.1. General
A separate ISBN must be assigned to every title, or edition of a title by each publisher, but NOT to an unchanged impression or unchanged reprint of the same title in the same format by the same publisher. Revised editions require a new ISBN. A price change does not call for a new ISBN. Changes of the format induce a new ISBN. The same title being published in a series and individually is treated as two different editions.

Given that the prefix of an ISBN refers to a specific publisher, then you would need a new ISBN.

www.isbn.org is an excellent reference for these types of questions.
