About this topic
The World Trade Organisation (WTO) is the international organisation that governs trade between states. This topic covers the functions of the WTO, its history from the 1930s tariff wars through Bretton Woods and GATT to the Marrakesh Agreement, its agreements (the annexes), the two core rules of non-discrimination, the dispute settlement system, its institutional structure and decision-making, and the key facts asked in objective papers.
Picture the legal team of an Indian exporters' council receiving three queries:
- Neha exports silk sarees from Kanchipuram. A country called Northland charges her sarees a 12% duty, while identical sarees from a rival country pay 4%.
- Farhan runs a software firm in Pune. He asks whether any world trade rule protects the services he sells abroad.
- A Commerce Ministry officer asks whether a country that lost a trade dispute to India can simply block the ruling.
The answers to all three appear under Quick revision at the end.
The WTO in one picture
The WTO can be understood as three things under one roof:
- A rulebook: the set of agreements every member must obey.
- A negotiating table: where members bargain for new rules.
- A referee: which settles disputes between members.
Functions of the WTO: Article 3 of the Marrakesh Agreement
The Marrakesh Agreement created the WTO. Its Article 3 lists five functions: the three above, plus two more.
- The rulebook: the agreements that bind members.
- The negotiating table: a forum for bargaining on new rules.
- The referee: settlement of disputes between members.
- The mirror: the Trade Policy Review Mechanism, which examines each member's trade policy in public.
- The neighbours: cooperation with the International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (IBRD).
On the fifth function, Article 3, paragraph 5 provides:
"With a view to achieving greater coherence in global economic policy-making, the WTO shall cooperate, as appropriate, with the International Monetary Fund and with the International Bank for Reconstruction and Development and its affiliated agencies."
Why these two institutions? History explains it: the IMF and the IBRD were the two pillars of the post-war economic order, and a trade body was planned as the third (see below).
Five functions under Article 3 of the Marrakesh Agreement: rulebook, negotiating table, referee, mirror (Trade Policy Review Mechanism) and neighbours (cooperation with the IMF and the IBRD under Article 3, paragraph 5).
Historical background
Private and public trade law
Trade law itself is old. Medieval merchants built their own customs, called lex mercatoria, or the law merchant. That tradition still shapes private trade law between traders. The WTO belongs to the public side of trade law, which binds states.
Lex mercatoria (law merchant) = customs built by medieval merchants; it shapes private trade law between traders. The WTO is public trade law; it binds states.
The 1930s: tariff walls
Public trade law was born from a disaster. In the 1930s, countries answered the Great Depression by raising tariffs, which are customs duties on imports. Each tariff wall invited a higher wall in return, and world trade collapsed.
The Bretton Woods Conference, 1944
- Formal name: United Nations Monetary and Financial Conference.
- Place: Bretton Woods, New Hampshire, United States.
- Dates: 1 July to 22 July 1944, before the Second World War had ended. The Allied nations met there.
- Participation: 730 delegates from 44 nations.
- Work: it designed the post-war money system and produced two institutions.
| Institution | Role |
|---|---|
| International Monetary Fund (IMF) | To keep exchange rates steady and help countries short of foreign currency. |
| International Bank for Reconstruction and Development (IBRD) | To lend to rebuild war-damaged countries, and later to fund development. The IBRD became the first member of today's World Bank Group. |
These two were the two pillars of the new economic house.
The International Trade Organisation that never came to life
- A third pillar was planned for trade: the International Trade Organisation (ITO).
- Its charter was adopted at Havana, Cuba, in March 1948.
- The United States Congress never approved it, and in 1950 the American government stopped trying.
- A trade body without the world's biggest trader made little sense, so the ITO never came to life.
GATT 1947: the stopgap
- Even before Havana, 23 countries, India among them, signed a shorter tariff agreement at Geneva on 30 October 1947. This was the General Agreement on Tariffs and Trade (GATT).
- Its provisional application began on 1 January 1948, as a stopgap until the ITO arrived.
- The ITO never arrived, so this temporary arrangement governed world trade for 47 years, until the WTO began in 1995.
GATT was like a tent pitched for one night, in which the world then lived for 47 years. Remember: signed 30 October 1947 at Geneva by 23 countries including India; provisional application from 1 January 1948.
The eight GATT rounds
Under GATT, members held eight rounds of bargaining:
| No. | Round | Memory aid |
|---|---|---|
| 1 | Geneva (1947) | European venue |
| 2 | Annecy | European venue |
| 3 | Torquay | European venue |
| 4 | Geneva (again) | Geneva again |
| 5 | Dillon Round | Named after an American |
| 6 | Kennedy Round | Named after an American |
| 7 | Tokyo Round | Named after its launch venue |
| 8 | Uruguay Round (opened at Punta del Este in 1986) | Named after its launch venue |
Order of the rounds: three European venues (Geneva 1947, Annecy, Torquay), then Geneva again, then two Americans (Dillon, Kennedy), then two named after their launch venues (Tokyo, and finally Uruguay, opened at Punta del Este in 1986).
Weaknesses of GATT
- GATT was a provisional agreement, not a true organisation.
- It covered only goods.
- Its referee had no teeth: a panel report needed consensus, so the losing country could block the verdict against itself.
Birth of the WTO
The Uruguay Round replaced the tent with a permanent building.
- The Marrakesh Agreement was signed in Morocco on 15 April 1994.
- The WTO began on 1 January 1995, with India as a founding member.
- Legal personality: under Article 8, the WTO has legal personality, that is, it exists in law in its own right.
The preamble names the goal of the WTO:
"the substantial reduction of tariffs and other barriers to trade and to the elimination of discriminatory treatment in international trade relations"
The WTO as GATT's successor
The old tent was not thrown away; its poles were reused.
- The old rules live on as GATT 1994, which Article 2, paragraph 4 calls "legally distinct" from GATT 1947.
- Article 16 tells the WTO to be "guided by the decisions, procedures and customary practices" of the GATT years.
That is why the WTO is called GATT's successor.
| Point | GATT 1947 | WTO |
|---|---|---|
| Nature | Provisional agreement, not a true organisation | Permanent organisation with legal personality (Article 8) |
| Start | Provisional application from 1 January 1948 | Began on 1 January 1995 |
| Coverage | Goods only | Goods (GATT 1994), services (GATS) and intellectual property (TRIPS) |
| Panel reports | Needed consensus; the losing country could block the report | Negative (reverse) consensus; the loser cannot block the report alone |
The WTO rulebook: the annexes
Beneath the Marrakesh umbrella hang the annexes:
| Annex | Contents |
|---|---|
| Annex 1A | The agreements on trade in goods, led by GATT 1994 |
| Annex 1B | General Agreement on Trade in Services (GATS) |
| Annex 1C | Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) |
| Annex 2 | Dispute Settlement Understanding (DSU) |
| Annex 3 | Trade Policy Review Mechanism (TPRM) |
| Annex 4 | Plurilateral agreements, which bind only those members who accept them |
The single undertaking
Under Article 2, Annexes 1, 2 and 3 are "binding on all Members". This is the single undertaking: no member can pick only the agreements it likes. Annex 4 is the exception, since its plurilateral agreements bind only those who accept them.
Single undertaking: Annexes 1, 2 and 3 bind every member (Article 2); a member cannot choose only the agreements it likes. Only the plurilateral agreements of Annex 4 are optional and bind those who accept them.
The two core rules: non-discrimination
Two rules form the spine of the WTO rulebook.
Most-favoured-nation treatment: Article 1 of GATT
"any advantage, favour, privilege or immunity granted by any contracting party to any product originating in or destined for any other country shall be accorded immediately and unconditionally to the like product originating in or destined for the territories of all other contracting parties."
Simply put, a favour to one member is a favour to all.
National treatment: Article 3 of GATT
Imported goods must receive "treatment no less favourable than that accorded to like products of national origin".
Imported shoes cannot be made to face a costly safety test that locally made shoes escape.
Exceptions
Both rules have exceptions. Free trade areas (Article 24 of GATT) and preferences for developing countries (the Enabling Clause) are exceptions to most-favoured-nation treatment. National treatment has its own exceptions, such as purchases by governments for their own use (Article 3, paragraph 8 of GATT).
Updated from the lecture: the lecture gave free trade areas and preferences for developing countries as exceptions to both rules. The correct position is that these two are exceptions to most-favoured-nation treatment; the Enabling Clause applies "Notwithstanding the provisions of Article I" of GATT, while national treatment has its own exceptions, such as government procurement under Article 3, paragraph 8. Source: WTO, Enabling Clause (1979) and WTO, Understanding the WTO: Principles of the trading system.
| Point | Most-favoured-nation treatment | National treatment |
|---|---|---|
| Provision | Article 1 of GATT | Article 3 of GATT |
| Core idea | A favour to one member is a favour to all | Imported goods must not be treated less favourably than like domestic goods |
| Comparison made | Like products from different foreign countries | Imported products against like products of national origin |
| Manner | Advantage to be given "immediately and unconditionally" | "treatment no less favourable" |
Dispute settlement
A rulebook needs a referee. The Dispute Settlement Understanding (DSU) cured GATT's weakness. The system is run by the Dispute Settlement Body (DSB).
Adoption of panel reports: Article 16(4) of the DSU
A panel report "shall be adopted at a DSB meeting unless a party to the dispute formally notifies the DSB of its decision to appeal or the DSB decides by consensus not to adopt the report."
Negative (reverse) consensus
Article 16(4) reverses the old GATT position:
| Point | Under GATT | Under the WTO (DSU) |
|---|---|---|
| What stops a report | One objection could stop a report | Every member, the winner included, must agree to stop it |
| Position of the loser | Could block the verdict against itself | Cannot block the report alone |
| Rule | Consensus needed to adopt | Negative or reverse consensus: adopted unless all agree not to adopt |
Negative (reverse) consensus: a panel report is adopted unless a party appeals or the DSB decides by consensus not to adopt it. Because every member, the winner included, must agree to stop a report, the loser cannot block it alone.
The Appellate Body
- Appeals go to the Appellate Body, on issues of law only.
- Since December 2019, blocked appointments have left the Appellate Body unable to hear appeals.
- As a result, a losing party can "appeal into the void", leaving the panel report unadopted.
- Some members use an interim appeal arbitration arrangement instead.
Institutional structure of the WTO
The WTO can be pictured as a building of three floors: the Ministerial Conference (top floor), the General Council (middle floor) and the Secretariat (ground floor).
Ministerial Conference (top floor)
Article 4, paragraph 1 provides:
"There shall be a Ministerial Conference composed of representatives of all the Members, which shall meet at least once every two years."
- It is the highest authority of the WTO.
- The first Ministerial Conference met in Singapore in 1996.
- The fourteenth met in Yaoundé, Cameroon, in March 2026.
Decision-making: Article 9
Article 9, paragraph 1 opens:
"The WTO shall continue the practice of decision-making by consensus followed under GATT 1947."
A footnote explains that consensus exists "if no Member, present at the meeting when the decision is taken, formally objects to the proposed decision."
Voting
- Only if consensus fails is there a vote.
- Each member has one vote.
- When the European Union votes, it gets as many votes as its member states that are WTO members, never more.
| Decision | Majority required |
|---|---|
| Ordinary decisions | Majority of votes cast |
| Authoritative interpretation | Three-fourths of the members |
| Waiver | Three-fourths of the members |
| Approving a new member's accession | Two-thirds |
Consensus first, vote only if consensus fails. Remember the thresholds: majority of votes cast for ordinary decisions; three-fourths of the members for an authoritative interpretation or a waiver; two-thirds for accession. Consensus means no member present formally objects.
General Council (middle floor)
- Since the Ministerial Conference meets only once in two years, the General Council keeps the lights on in between.
- It is again composed of all members, usually represented by their ambassadors in Geneva, and does the Conference's work between its sessions.
- It wears two more hats:
- as the Dispute Settlement Body, it runs the referee;
- as the Trade Policy Review Body, it holds the mirror.
- Under it sit three councils: for goods, for services and for TRIPS.
The same body of all members acts in three capacities: General Council, Dispute Settlement Body and Trade Policy Review Body.
Secretariat (ground floor)
- The Secretariat is headed by a Director-General.
- Under Article 6, "The Ministerial Conference shall appoint the Director-General". Between conferences, the General Council exercises this power.
- The staff support the councils, train officials from developing countries, study trade data and inform the public.
- The Secretariat decides nothing, because the WTO is member-driven.
The WTO at a glance
| Item | Fact |
|---|---|
| Created by | Marrakesh Agreement, signed 15 April 1994 |
| Began | 1 January 1995 (India a founding member) |
| Headquarters | Geneva, Switzerland |
| Official languages | English, French and Spanish, because the Agreement was done "in the English, French and Spanish languages, each text being authentic." |
| Members | 166 |
| 164th member | Afghanistan (July 2016) |
| Latest members | Comoros and then Timor-Leste (August 2024); Timor-Leste is the latest |
| Observer governments | 22 |
| Director-General | Ngozi Okonjo-Iweala of Nigeria, the first woman and first African in the post, now in her second term |
| Relation with the UN | Not a UN specialised agency; rests on its own treaty, though it cooperates with the UN |
Updated from the lecture: the lecture gave 23 observer governments. The correct position is that the WTO now lists 22 observer governments, alongside 166 members, after Comoros and Timor-Leste moved from observer to member in 2024. Both figures change as new members join. Source: WTO, Members and Observers.
Exam trap: the WTO is not a United Nations specialised agency, unlike the World Health Organisation or UNESCO. It rests on its own treaty, though it cooperates with the UN. Strangely, the IMF and the World Bank are UN specialised agencies, so the two Bretton Woods pillars joined the UN family while the trade pillar stayed outside.
Quick revision
- The picture: the WTO is a rulebook (agreements), a negotiating table (new rules) and a referee (dispute settlement) under one roof.
- Neha's problem (most-favoured-nation treatment): if both countries are WTO members and no exception, such as a free trade agreement, applies, Northland must give Neha's sarees the same 4% duty.
- Farhan's problem (services): services had no global rulebook under GATT. Protection began in 1995 through GATS, and its reach depends on each country's commitments.
- The officer's question (dispute settlement): negative consensus stops the loser from blocking the report alone. But while the Appellate Body is frozen, the loser can appeal into the void, unless both sides accepted interim appeal arbitration.
