Another principle that is equally important in
international trade law regimes is transparency. This
principle encourages countries to use transparent
instruments in drafting and operating trade policies.
Transparency principle has three extensive sets of
meaning: (1) the legal instruments governing
international trade are known, clear and
comprehensible to the trade actors; (2) the objectives
and purposes of the treaty are reflected adequately in
its text; and (3) the objectives and purposes of the
treaty are respected and achieved sufficiently in its
application and implementation (International Trade
Centre, 2010). This principle also encourages the
realization of predictability, an indispensable
condition in business processes. Providing security
and predictability to the rule-oriented multilateral
trading system reflects under Article 3.2 Dispute
Settlement Understanding (DSU) as in the interest of
the stability, legal certainty, consistency, and an
increased persuasive power of the reports, it is
required by the function of the dispute settlement
system to provide security and predictability (Weiss,
2003).
The above three principles, namely fairness, non-
discrimination and transparency are further set forth
in some of the more specific norms in the WTO
Agreement. This norm is the provision of Most
Favoured Nations (MFN) and National Treatment
(NT). Under the terms of the MFN, each WTO state
member shall accord equal treatment to all other
WTO member states. When a WTO member grants
certain favourable treatment to one country shall
grant the same favourable treatment to all WTO
members (Bossche, 2005). MFN obligation is not
only concerning any advantages granted to other
WTO members, but also any advantages to all other
countries including non-WTO members (Bossche,
2005).
Article I.1 General Agreement on Tariffs and
Trade (GATT) regulates that any advantages,
favours, privileges or immunities granted in one
country, shall immediately and unconditionally be
offered to the like-products of all WTO members. In
short, the scope of advantages, favours, privileges or
immunities granted are: (1) custom duties, other
charges on imports and exports and other customs
matters; (2) internal taxes; and (3) internal regulation
affecting the sale, distribution and use of products.
Furthermore, the term ‘immediately’ means that there
must be no delay in extending any advantage granted
to all WTO members (Mitsuo Matsushita, 2006).
While the term ‘unconditionally’ means that it is not
limited by or subject to any conditions such as
requirement of compensation (Mitsuo Matsushita,
2006), asking something in return or paying for the
advantage (Bossche, 2005).
While NT requires all WTO members to treat
foreign products and/or services not less favourably
than the treatment of like domestic products and/or
services. It means that states shall provide equal
treatment in sales, taxation and regulation of imported
goods/services and domestic goods/services
(Bossche, 2005). The provision of NT is set forth in
Article III GATT implies that no law, regulations or
taxation condition may adversely differentiate the
conditions of competition between like foreign and
domestic products in the domestic market (Mitsuo
Matsushita, 2006). This article has purpose to limit
national protective measures to border controls and
secures equality of opportunity for imported products
to be competed with domestic products (Mitsuo
Matsushita, 2006). Article III.1 regulates the scope of
NT application: (1) internal taxes and charges; (2)
laws, regulations and requirements affecting the
internal sale, offering for sale, purchase,
transportation, distribution or use of products; and (3)
internal quantitative regulations requiring the
mixture, processing or use of products in specified
amounts or proportions.
In relation to transparency, the WTO Agreement
encourages state members to use tariff barriers to
control the flow of goods and services. Similarly, any
regulatory changes should be accessible and
understandable by international trade actors to avoid
misunderstanding as it is reflected under the preamble
of WTO Agreement that in pursuing the objectives,
WTO members enter into reciprocal and mutually
advantageous arrangements directed to the
substantial reduction of tariffs and other barriers to
trade.
One of the basic purposes of GATT is to reduce
and bind tariffs by put it in Schedule of Concession.
Article II.1(a) of GATT is established to protect the
tariff bindings, obligating WTO members to accord
tariff treatment no less favourable than that provided
in their Schedules. While Article II.1(b) regulates that
there must be no ordinary customs duties and all other
duties in excess of those notified in the submitted
schedule (Bossche, 2005). Other instruments such as
quotas and import licenses (non-tariff barriers) are
still allowed but not recommended because they are
often be changeable and unpredictable in both time
and quantity. Tariff remains important trade barriers
because most developing-country members still
apply high custom duties because it can increase the
economic development. Moreover, in very
competitive markets between neighbouring countries,
