The World Trade Organization (WTO) is an international organization that administers negotiated rules governing trade among its members. Established on 1 January 1995 and headquartered in Geneva, Switzerland, it provides a forum for negotiations, operates a dispute-settlement system, reviews members’ trade policies, and supplies technical assistance. Its agreements cover goods, services, and intellectual property. The WTO is governed by its members rather than by an independent authority empowered to determine trade policy. (wto.org)
Origins and establishment
The WTO developed from the General Agreement on Tariffs and Trade (GATT), concluded in 1947. Successive negotiating rounds under GATT reduced trade barriers and expanded the rules governing merchandise trade. The Uruguay Round, conducted between 1986 and 1994, extended this framework to services and intellectual property and produced a permanent international organization. (wto.org)
The Marrakesh Agreement, signed on 15 April 1994, established the WTO and entered into force on 1 January 1995. Although the WTO succeeded the institutional arrangements associated with GATT, it did not simply abolish the agreement. GATT 1994 remains the principal framework for trade in goods within the WTO system and is legally distinct from GATT 1947. The WTO brought the principal agreements under a common institutional structure, including procedures for dispute settlement and policy review. (wto.org)
Membership and governance
Following the accessions of Comoros and Timor-Leste in August 2024, the WTO had 166 members, accounting for approximately 98 percent of world trade. Membership is not restricted to sovereign countries: the founding agreement also permits separate customs territories possessing autonomy over their external commercial relations to join. The European Union is itself a member alongside its member states. Accession requires negotiation of membership terms and trade commitments. (wto.org)
The highest decision-making institution is the Ministerial Conference, which must meet at least once every two years. Between conferences, the General Council conducts the organization’s business. It also convenes as the Dispute Settlement Body and the Trade Policy Review Body. Specialized councils oversee goods, services, and intellectual property, supported by committees addressing particular agreements and subjects. (wto.org)
Decisions are normally made by consensus, although the founding agreement provides voting procedures for specified circumstances. The Secretariat supplies administrative, technical, and analytical support; it does not exercise the decision-making powers of the membership. Funding comes principally from members’ contributions, calculated with reference to their shares of international trade. English, French, and Spanish are the organization’s working languages.

Agreements and core principles
Three central agreements organize the WTO’s substantive coverage. GATT addresses goods; the General Agreement on Trade in Services (GATS) governs services; and the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) establishes obligations concerning intellectual property. Other agreements regulate agriculture, subsidies, anti-dumping measures, customs valuation, product standards, and related matters. Members’ schedules record specific market-access commitments.

Non-discrimination has two principal forms:
- Most-favoured-nation treatment: a trade advantage granted to one trading partner generally must be extended to other WTO members, subject to authorized exceptions.
- National treatment: imported products generally must not receive less favourable treatment than comparable domestic products concerning internal taxation and regulation. The principle also appears in GATS and TRIPS, with different scopes and conditions. (wto.org)
Predictability is supported by tariff bindings: negotiated ceilings above which import duties ordinarily cannot rise without prescribed renegotiation procedures. Applied tariffs may be lower than these ceilings. Transparency requirements include publication and notification of trade measures, while policy reviews provide additional scrutiny. (wto.org)
WTO rules do not require unrestricted trade in every circumstance. Agreements recognize exceptions and conditional flexibilities, including certain regional trade arrangements and measures protecting health or the environment. Whether a measure is permitted depends on the relevant agreement and its legal requirements, rather than merely on its stated objective. (wto.org)
Dispute settlement
The Dispute Settlement Understanding establishes procedures through which members challenge measures allegedly inconsistent with WTO obligations. Proceedings ordinarily begin with consultations. If these do not resolve the matter, a panel may examine the claims and issue a report. The system is intergovernmental: private companies do not bring complaints directly. (wto.org)
Important procedural decisions use “negative consensus,” meaning that specified actions proceed unless all members agree to stop them. This limits a respondent’s ability to block proceedings unilaterally. When an adopted ruling finds a violation, the preferred outcome is compliance. Continued non-compliance may eventually lead to authorization for the complainant to suspend trade concessions; retaliation is not an automatic penalty. (wto.org)
The Appellate Body was established to review legal issues in panel reports. In December 2019, vacancies left it unable to form the three-member divisions required to hear new appeals. Panel proceedings continued, but the loss of functioning appellate review created difficulties in completing appealed disputes. (wto.org)
Development, negotiations, and monitoring
WTO agreements contain special and differential treatment provisions for developing and least-developed members. These include longer implementation periods, measures supporting trading opportunities, and assistance with institutional capacity and technical standards. Their content and legal force vary between agreements. (wto.org)
Negotiations also modify and extend the rulebook. The Doha Development Agenda was launched in November 2001. A later agreement, the Trade Facilitation Agreement, entered into force on 22 February 2017. It addresses the movement, release, and clearance of goods, including customs procedures, and links some developing-country implementation commitments to assistance and capacity-building. (wto.org)
The Trade Policy Review Mechanism examines members’ policies through reports and collective discussion. Unlike dispute settlement, its purpose is transparency and understanding rather than adjudication of particular legal claims. Alongside negotiations and enforcement, these reviews constitute a continuing function of the organization. (wto.org)
