What Is the WTO? How the World Trade Organization Shapes Global Commerce

When Donald Trump imposed tariffs on steel and aluminium in 2018, dozens of countries complained to the World Trade Organization (WTO), arguing that the tariffs violated international trade rules. The WTO ruled against the US, but Trump ignored the ruling and kept the tariffs in place. It was a stark illustration of the WTO's power — and its limits. The WTO sets the rules for global trade, settles disputes, and tries to prevent trade wars, but it cannot force countries to comply. Here is what the WTO is, how it works, and why it matters in an age of rising protectionism and trade tensions.

What the WTO Is

The World Trade Organization (WTO) is an international organization that regulates trade between countries. It was created in 1995, replacing the General Agreement on Tariffs and Trade (GATT), which had governed trade since 1947.

The WTO has 164 member countries, representing 98% of world trade. Members agree to follow WTO rules on tariffs, subsidies, intellectual property, and services, and to settle trade disputes through the WTO's dispute settlement system.

The WTO is headquartered in Geneva, Switzerland, and is funded by member contributions based on their share of world trade.

What the WTO Does

1. Sets trade rules

The WTO administers trade agreements negotiated by member countries. The main agreements cover:

• Goods (GATT) — rules on tariffs, quotas, and subsidies for physical products
• Services (GATS) — rules on trade in services like banking, telecommunications, and tourism
• Intellectual property (TRIPS) — rules on patents, copyrights, and trademarks
• Agriculture — special rules on farm subsidies and tariffs
• Textiles and clothing — rules on quotas and tariffs (now mostly phased out)

The core principle is non-discrimination: countries must treat all WTO members equally (most-favoured-nation treatment) and must not discriminate between domestic and foreign products (national treatment).

2. Negotiates trade liberalisation

The WTO hosts trade rounds — multi-year negotiations to reduce tariffs and trade barriers. The most recent is the Doha Round, launched in 2001 to help developing countries. It has stalled due to disagreements between rich and poor countries over agriculture, services, and intellectual property.

Before Doha, the Uruguay Round (1986–1994) created the WTO and significantly reduced tariffs on goods.

3. Settles disputes

The WTO's dispute settlement system is its most important function. When countries disagree about trade rules, they can bring a case to the WTO. A panel of experts hears the case and issues a ruling. If a country loses, it must comply or face retaliation (counter-tariffs).

Since 1995, the WTO has handled over 600 disputes, making it the world's busiest international court. Cases have covered everything from US steel tariffs to EU banana import rules to China's intellectual property enforcement.

4. Monitors trade policies

The WTO reviews members' trade policies through Trade Policy Reviews, which assess whether countries are complying with WTO rules. This creates transparency and peer pressure to follow the rules.

How the WTO Works

Decision-making

The WTO operates by consensus — all 164 members must agree on decisions. This makes reform slow and difficult, because any country can block a proposal.

The WTO is governed by:

• The Ministerial Conference — the highest decision-making body, meeting every two years
• The General Council — day-to-day decision-making, meeting regularly in Geneva
• Specialized councils — covering goods, services, intellectual property, etc.

Voting

In theory, the WTO can take decisions by majority vote (one country, one vote), but in practice, decisions are made by consensus. This gives small countries more power than in institutions like the IMF or World Bank, where voting is weighted by economic size.

The Dispute Settlement System

The WTO's dispute settlement system is a three-stage process:

1. Consultations

Countries must first try to resolve the dispute through negotiations. If this fails after 60 days, the complaining country can request a panel.

2. Panel

A panel of three trade experts hears the case and issues a ruling (usually within 6–9 months). The ruling is based on WTO agreements, not on what is fair or good policy.

If a country loses, it must comply (remove the offending policy) or negotiate compensation (e.g., lower tariffs on other products).

3. Appellate Body

Either side can appeal the panel's ruling to the Appellate Body, a standing group of seven trade law experts. The Appellate Body reviews the legal reasoning (not the facts) and issues a final ruling (usually within 90 days).

Appellate Body rulings are binding, and countries almost always comply. But the system has no enforcement mechanism — if a country refuses to comply, the WTO can authorise the winning country to impose retaliatory tariffs (counter-measures).

The Appellate Body crisis

From 2017 to 2020, the US blocked appointments to the Appellate Body, arguing that it was overstepping its mandate and creating new rules. By December 2019, the Appellate Body had only one member left (it needs three to hear a case), effectively paralysing the system.

This was a major blow to the WTO. Countries can still bring disputes to panels, but without an Appellate Body, losing countries can appeal into the void, preventing rulings from becoming final.

In 2020, the EU and other countries created an interim appeal system (the Multi-Party Interim Appeal Arbitration Arrangement, or MPIA) to bypass the Appellate Body. The US has not joined, and the system remains in limbo.

The UK and the WTO

The UK has been a WTO member since 1995 (as part of the EU) and became an independent member after Brexit in 2020. The UK now negotiates its own trade policy and can bring WTO disputes independently.

Brexit required the UK to establish its own tariff schedule (the rates it charges on imports) and services commitments at the WTO. The UK largely copied the EU's schedules, but some countries (including the US, Australia, and New Zealand) objected, arguing that the UK should get a smaller share of tariff-rate quotas (limits on low-tariff imports of products like beef and lamb).

The UK is a strong supporter of the WTO and has called for reform of the dispute settlement system and the Appellate Body.

The Criticisms

The WTO has been criticised from both left and right:

1. It favours rich countries

Critics argue that WTO rules are written by and for rich countries and multinational corporations. Developing countries have less negotiating power and struggle to comply with complex WTO rules.

For example, the TRIPS agreement (on intellectual property) requires countries to enforce patents on medicines, which critics say prevents poor countries from accessing affordable drugs.

2. It undermines sovereignty

The WTO can rule that a country's laws violate trade rules, forcing the country to change its laws or face retaliation. Critics argue this undermines democracy and national sovereignty.

For example, the WTO ruled against the EU's ban on hormone-treated beef (from the US), arguing it was not based on scientific evidence. The EU refused to lift the ban, and the US imposed retaliatory tariffs.

3. It promotes a race to the bottom

Critics argue that free trade encourages countries to lower labour and environmental standards to attract investment and boost exports. The WTO has no rules on labour rights or environmental protection (except for a few exceptions).

4. It is too slow

The Doha Round has been stuck for over 20 years, and the WTO has struggled to adapt to new issues like digital trade, e-commerce, and climate change. Critics say the consensus rule makes the WTO too slow to respond to a fast-changing world.

5. It is toothless

The WTO can authorise retaliation, but it cannot force countries to comply with rulings. Powerful countries (like the US and China) can ignore WTO rulings with limited consequences.

The Defences

Supporters argue that:

1. It prevents trade wars

The WTO provides a rules-based system that prevents countries from imposing arbitrary tariffs and starting trade wars. Before the WTO (and GATT), trade wars were common and contributed to the Great Depression.

2. It promotes prosperity

Free trade increases efficiency, lowers prices, and promotes economic growth. The WTO has helped reduce tariffs from an average of 40% in 1947 to less than 5% today, boosting global trade and lifting millions out of poverty.

3. It gives small countries a voice

The WTO's consensus rule and dispute settlement system give small countries more power than they would have in bilateral negotiations with large countries. A small country can win a WTO case against the US or EU.

4. It is better than the alternative

Without the WTO, trade would be governed by bilateral deals and power politics, favouring the strongest countries. The WTO is imperfect, but it is better than no rules at all.

The Future of the WTO

The WTO faces several challenges:

1. US-China tensions

The US and China are locked in a trade war, with both sides imposing tariffs and accusing each other of violating WTO rules. The WTO has struggled to mediate, and some fear the organisation will become irrelevant if the world's two largest economies ignore it.

2. The Appellate Body crisis

The dispute settlement system remains paralysed, and there is no agreement on how to fix it. Some countries want to reform the Appellate Body to address US concerns; others want to restore it as it was.

3. Digital trade and e-commerce

The WTO has no comprehensive rules on digital trade, e-commerce, data flows, or digital taxation. Some countries are negotiating a plurilateral agreement (among willing members), but progress is slow.

4. Climate change

The WTO has no rules on carbon tariffs or climate-related trade measures. The EU's Carbon Border Adjustment Mechanism (CBAM), which taxes imports based on their carbon footprint, may be challenged at the WTO.

5. Regionalism

Countries are increasingly negotiating regional trade agreements (like the EU, USMCA, CPTPP) outside the WTO. These agreements go beyond WTO rules and risk fragmenting the global trading system.

The Bottom Line

The WTO has 164 member countries representing 98% of world trade, with rules covering tariffs, subsidies, intellectual property, and services. The WTO's dispute settlement system has resolved over 600 trade disputes since 1995, acting as the world's trade court. Decisions require consensus of all members, making reform difficult — the Doha Round launched in 2001 has still not concluded. The US blocked appointments to the WTO's appellate body from 2017-2020, effectively paralysing the dispute system. Critics say the WTO favours rich countries and corporations over developing countries and workers, while supporters say it prevents trade wars and promotes prosperity. The WTO faces major challenges including US-China tensions, the Appellate Body crisis, digital trade, climate change, and the rise of regional trade agreements. The WTO is imperfect, slow, and often toothless, but it remains the only global forum for setting trade rules and settling disputes. In an age of rising protectionism and trade tensions, the WTO's role is more important than ever — even if its power is limited.
