Legality of "Southeast-Asia Restricted Edition" textbooks being sold in the U.S.?

[Rigamarole]

In researching this topic I was furnished with this link from Google Answers that asks essentially the same question I want to know: Is it legal for sellers to sell these books marked “For Sale only in India, etc.” within the U.S.?

The link is very exhaustive and difficult to parse completely, but it says in closing:

@Google Answers

Therefore, the current state of US law is that international versions
of textbooks that are lawfully manufactured under the authorization of
the copyright holder can be legally imported by a party that has
acquired them outside of the US, for subsequent resale within the US.
While the copyright holder can require that their license holders (the
international printers) do not themselves ship manufactured copies
directly for public distribution in the US without prior consent, the
copyright holder cannot prevent a party from purchasing lawfully
manufactured copies outside the US, and importing them into the US for
sale or otherwise disposal.

However, this thread was posted 10 Jan 2004. Can anyone verify/confirm if the Google Answers are indeed correct (and still current) on this issue?

AFAIK, nothing has changed.
