This article is a follow-up to the FAL Bulletin No. 167, in the sense that it considers developments in trade facilitation within WTO. Its focus, however, is exclusively on what has occured within WTO in this area. Emphasis is placed not only on expanding on, but also on updating the relevant background information presented on the Subject in FAL No. 167. An attempt has been made to incorporate some analytical elements into an orientation that is primarily descriptive.
