Whilst presumably not mentioning all the chess books the USCF bought
in Serbia.

That's a good point.

How did the USCF continue to import Yugoslav chess books (such as Informants)
during the period of United States economic sanctions against Yugoslavia?

I read something to the effect that the USCF simply continued to receive
these books during the embargo,

From 12810:

***BEGIN***

importation;

I'm not sure of the ramifications of the 'notwithstanding' clause here.
Maybe someone with more US legal knowledge than I have, could advise?

while not bothering to send payment until
afterward (if at all).

Out of interest, did any US journalists go to Sveti Stefan to report the
match? If they did, who paid their hotel bills?
