IMPLEMENTATION OF SPECIAL AND DIFFERENTIAL TREATMENT
PROVISIONS IN WTO AGREEMENTS AND DECISIONS
MANDATORY AND NON-MANDATORY SPECIAL AND
DIFFERENTIAL TREATMENT PROVISIONS
Note by the Secretariat
Addendum
INTRODUCTION
This note responds to the request made by delegations, pursuant to paragraph 12.1 (i) of the
Decision on implementation-related issues and conc erns adopted at Doha (WT/MIN(01)/17), that the
Secretariat identify mandatory and non-mandatory special and differential treatment provisions.  Apreliminary identification was made in WT/COMTD/W/77/Rev.1.  This paper, which consolidates
and completes the information found in that document, accompanies the Secretariat note "A Review
of Mandatory Special and Differential Treatment Provisions".
The note is organized according to the six substantive categories of special and differential
treatment provisions used in previous Secretariat documentation:  (i) provisions aimed at increasing
the trade opportunities of developing country Me mbers;  (ii) provisions under which WTO Members
should safeguard the interests of developing country Members;  (iii) flexibility of commitments, of
actions, and use of policy instruments;  (iv) transitional time periods;  (v) technical assistance;  and
(vi) provisions relating to least-developed country Members.  It is recalled that provisions in
Category (vi) all fall into one of the other five categories, but are distinctive insofar as their
application relates exclusively to least-developed countries.
The focus of the note is on categories (i), (ii) and (v) above, as well as certain provisions
falling under category (vi) for which the distinction between mandatory and non-mandatory is
relevant.  Mandatory provisions are distinguished from non-mandatory provisions on the basis of the
following rule:  mandatory provisions use "shall" language; non-mandatory provisions use "should"language.  The distinction between "mandatory" and "non-mandatory" provisions does not apply to
provisions under Categories (iii) and (iv), and some corresponding provisions within Category (vi).
These specify levels of flexibility and transition time periods that developing countries may choose to
exercise should they so wish.WT/COMTD/W/77/Rev.1/Add.1
