WTO: Historical Evolution, Core Principles & Contemporary Challenges

  • Structure of today’s 3-hour session:

    1. Historical evolution of global trade rules.

    2. Core structure & principles of WTO.

    3. Class exercises (comparative advantage + Sri Lankan sectors).

  • Pedagogic method: Combination of PowerPoint, hand-outs (pages from lecturer’s 2016 book Global Trade & Sri Lanka) and interactive break-out rooms.

Contemporary Trigger: U.S. Tariff Policy & Global Uncertainty

  • Morning IP class discussed President Donald Trump’s “Most-Favoured-Nation (MFN) Pricing” for drugs; afternoon class extends discussion to tariffs on goods.

  • WTO Director-General warning (April 2020 article):
    • Forecast of global trade falling instead of expanding due to policy uncertainty.
    • Quote: “Trade-policy uncertainty has a significant dampening effect on trade flows.”

  • Observation: Trump administration announces very high tariffs, then negotiates lower ones → politically driven, unpredictable decisions ≠ purely economic analysis.

  • U.S. concern: high tariffs can weaken domestic economy; yet U.S. simultaneously enforces its legal entitlements “to the letter”.

  • Relevance: WTO cannot intervene ex ante; action only arises when a formal dispute is lodged.

Why Regulate International Trade?

  • Post-WWI & Great Depression experience: unilateral protectionism (high tariffs) → deepened recession.

  • “Beggar-Thy-Neighbour” policy:
    • States try to enrich themselves (via exports) while impoverishing trading partners (by blocking imports).
    • Logically flawed because “your export is somebody else’s import”.

  • Tariffs defined: a tax on imports, used to:

    1. Discourage foreign goods, protect domestic producers.

    2. Generate revenue for government.

  • Ethical & practical tension: Governments talk about “global welfare” yet each pursues national economic and political interests (reelection, strategic power).

Early Multilateral Efforts (1919-1947)

1 | Failure after WWI

  • Protectionist mood + economic fragility prevented consensus on a trade body.

  • Smoot–Hawley Tariff Act (1930, U.S.):
    • Last time U.S. Congress fixed actual tariff rates.
    • Triggered retaliation, loss of confidence, contraction of world trade.

2 | Bretton Woods Conference (UN Monetary & Financial Conference, Bretton Woods, New Hampshire, 1944)

  • Aimed at overall economic reconstruction; highlighted need for global trade regulator.

  • Outcomes:
    • Fixed exchange-rate system centred on US $ & gold (ended by President Nixon 1971).
    • Blueprint for an International Trade Organization (ITO).

3 | Abortive International Trade Organization

  • Draft ITO Charter completed 1948; required U.S. Congressional approval.
    • President Truman supported; Congress never ratified → ITO died.
    • U.S. simultaneously “creator & destroyer” of first trade body proposal.

Emergence of the General Agreement on Tariffs and Trade (GATT) 1947/48

  • Countries still committed to tariff discipline to avoid another 1930s scenario.

  • GATT = multilateral contractual code; ad hoc secretariat in Geneva.

  • Primary aim: regulate & reduce tariffs on traded goods.

  • Achievements 1948-1994:
    • Series of “Rounds” (Dillon, Kennedy, Tokyo, etc.) progressively lowered bound tariffs.
    • Provided stability, predictability, economic growth for members.

  • Limitations:
    • Covered goods only – not services or intellectual property.
    • Weak institutional structure (no real organisation, dispute procedure slow).

Pressure for Reform (1980s-early 1990s)

  • Factors:

  1. Rise of Japanese & NICs’ competitiveness.

  2. U.S. trade deficit and surges of protectionist measures.

  3. New trade areas: services, IP, agriculture subsidies.

  • Uruguay Round (1986-1994) negotiations:
    • Drafts: Anell, Dunkel texts—earlier drafts gave more concessions for developing countries than final text.
    • Culminated in Marrakesh Agreement Establishing the WTO (15 April 1994).

World Trade Organization (WTO)

Legal Status & Membership

  • WTO created 1 Jan 1995; successors to GATT rights & obligations.

  • Parties are “customs territories” – avoids direct sovereignty conflicts.
    • Example: Hong Kong (China) is separate member; EU is a member in its own right.

  • Article II(2) Marrakesh Agreement: All “multilateral trade agreements” (the covered agreements) are binding en bloc—no reservations permitted.

Institutional Organs

  • Ministerial Conference – supreme body, meets at least every 22 years.

  • General Council – permanent delegates in Geneva; also convenes as:
    • Dispute Settlement Body (DSB).
    • Trade Policy Review Body (TPRB).

  • 3 specialist Councils (per agreement):
    • Council for Trade in Goods.
    • Council for Trade in Services.
    • Council for Trade-Related Aspects of Intellectual Property Rights (TRIPS).

  • Secretariat headed by Director-General; conducts research, technical assistance.

Broad Objectives (Preambles)

  • GATT 1947: raise living standards, full employment, real income growth, optimal use of resources.

  • WTO 1995 adds:
    • Trade in services & IP.
    • Sustainable development.
    • “Positive efforts” for developing & least-developed countries (LDCs) to secure share of growth.

Four Core Legal Principles

1 | Most-Favoured-Nation (MFN) – GATT Art. I / GATS Art. II / TRIPS Art. 4

  • Any advantage (tariff reduction, licence condition, etc.) given to one WTO member must be extended immediately & unconditionally to all.

  • Exceptions:
    • Regional Trade Agreements (RTAs) / customs unions (GATT Art. XXIV, GATS V).
    • Generalised System of Preferences (GSP) for developing countries (Enabling Clause).

2 | National Treatment (NT) – GATT Art. III / GATS Art. XVII / TRIPS Art. 3

  • Imported products or foreign services/IP cannot be treated less favourably than like domestic products after they have cleared customs.

  • Example of violation: Extra fumigation rules that delay imported flowers but not domestic ones.

3 | Elimination of Quantitative Restrictions – GATT Art. XI

  • Prohibits quotas, import/export bans, discretionary licensing except under defined safeguards.

  • Linked disciplines:
    • Agreement on Subsidies & Countervailing Measures (SCM).
    • Agreement on Agriculture (AoA) – phase-out of export subsidies.

  • Economic rationale: Subsidy of 33 rupees on a good whose real cost is 88 lowers price to 55 → distorts competition & shifts burden to taxpayers.

4 | Tariff Binding & Harmonisation

  • Members bind maximum tariff rates in schedules using Nomenclature (Nice / HS codes).
    • Once bound, a tariff cannot be raised unilaterally above the ceiling without compensation (Art. XXVIII negotiations).

  • “Harmonised System (HS)” + “Nice Classification” ensure precise product definitions.

MFN + NT combined create a field where “all imports are equal, and all imports equal domestic goods”.

Other WTO Rules & Agreements (Selected)

  • Customs valuation, rules of origin.

  • Technical Barriers to Trade (TBT) & Sanitary/Phytosanitary (SPS) Measures.

  • Trade-Related Investment Measures (TRIMs).

  • Anti-Dumping Agreement (ADA) & Safeguards Agreement.

  • Dispute Settlement Understanding (DSU).

  • Trade Facilitation Agreement (TFA 2013-17 implementation).

  • Emerging topics: E-commerce, competition, government procurement, trade & environment.

Classroom Illustration: Comparative Advantage

Computers (cost)

Tea (cost)

State A

55

66

State B

1010

88

  • Absolute Advantage: State A cheaper in both goods.

  • Comparative Advantage (ratio):
    • Computers: 5/10=0.55/10 = 0.5 (A twice as efficient).
    • Tea: 6/8=0.756/8 = 0.75.

  • Larger gap in computers ⇒ State A should specialise in computers; State B in tea.
    • Frees global resources; both can trade to gain.

Ethical note: Comparative-advantage logic can widen trade imbalances; needs redistributive or adjustment policies for losers.

Break-Out Exercise (Sri Lanka case)

  • Students identified sectors where SL maintains production despite weak competitiveness: e.g. rice (due to food security & farmer livelihood), sugar, dairy, rubber goods, coconut-based products.

  • Discussion on whether to maintain vs phase-out included
    • socio-political imperatives (employment, rural welfare),
    • fiscal cost of subsidies,
    • possibility of upgrading efficiency.

Philosophical & Developmental Considerations

  • WTO frames itself as non-political, yet trade rules are inherently geo-political.

  • Developing countries accepted TRIPS, services, etc. in expectation of:

    1. Special & Differential Treatment (SDT),

    2. Restraint in “non-violation complaints”.

  • Current U.S. assertiveness raises fear that historical compromises are being reversed.

  • Debate: Export-led growth vs self-reliance – neither fully viable; balanced strategy & competitive upgrading required.

Practical Take-Aways for Exam & Practice

  1. Memorise four core WTO principles + exceptions.

  2. Understand historical causation: Smoot–Hawley → tariff wars → GATT → WTO.

  3. Be able to relate tariff/subsidy mechanics to real-world examples (e.g. Sri Lankan vehicles, Ecuador Bananas).

  4. Note institutional difference: WTO ≠ UN treaty – no reservations, membership = customs unions.

  5. For problem questions, always ask:
    • Is MFN/NT violated?
    • Is there a quantitative restriction?
    • Is tariff bound?
    • Are there covered-agreement defences (health, environment, security)?

Reading & Study Road-Map

  • Lecturer’s Book: Global Trade & Sri Lanka (2016) – pp. 5-8 for today’s content; further pages for agreements overview.

  • Ronald McKinnon, “Beggar-Thy-Neighbour Tariff Wars” (first 2 pages recommended).

  • Bretton Woods hand-out (UN Monetary & Financial Conf.).

  • WTO website: legal texts and “Understanding the WTO” booklet.

  • Next lecture preview:

Key Formulae / Numerical References (in LaTeX)

  • Subsidy price distortion: P<em>market=P</em>cost−SP<em>{market}=P</em>{cost}-S where SS is per-unit subsidy.

  • Comparative Advantage Ratio: CA<em>A,B=Cost</em>BCostACA<em>{A,B}=\frac{Cost</em>{B}}{Cost_{A}}; higher ratio ⇒ stronger comparative advantage for AA.

  • Tariff revenue: R=Qimport×tR = Q_{import} \times t where tt is ad-valorem tariff rate.

Concluding Thoughts

  • WTO remains “central nervous system” of global trade, but its credibility hinges on big powers honouring rules.

  • Developing & least-developed members must master legal disciplines to safeguard interests in the face of shifting geopolitics.

  • Historical literacy (Bretton Woods → Uruguary Round) is essential to interpret current events (e.g., U.S.–China tariffs, pandemic export bans).
