The WTO succeeded the General Agreement on Tariffs and Trade in 1995 with a strengthened mandate: binding dispute settlement through a two-tier Appellate Body, expanded coverage to services and intellectual property, and ambitions for further multilateral liberalization through the Doha Round. None of these ambitions fully materialized. The Doha Round collapsed. The Appellate Body was paralyzed when the United States — the institution's founding power — decided that rules-based adjudication was no longer in its interest. The WTO remains the formal architecture of international trade law, but the trade order it was designed to enforce is now managed through bilateral deals, tariff escalation, and strategic industrial policy that the institution cannot discipline.
The General Agreement on Tariffs and Trade was signed in 1947 as a provisional framework to lower tariffs and prevent the protectionist spirals that had amplified the Great Depression. Despite being conceived as temporary pending a never-ratified International Trade Organization, GATT functioned for 48 years through eight negotiating rounds, progressively reducing tariff barriers among developed economies. The WTO was created in 1995 to formalize and expand this framework — adding services (GATS), intellectual property (TRIPS), binding dispute settlement, and near-universal membership.
China's accession in 2001 was the institution's defining moment — and the source of its central contradiction. The WTO's rules were designed for market economies; China's state capitalist model — subsidized state enterprises, managed exchange rates, technology transfer requirements — created persistent friction with WTO norms that the dispute settlement system proved unable to resolve at the systemic level. The US position that China never genuinely complied with its WTO accession commitments is the proximate cause of the Appellate Body crisis.
The WTO performs three core functions. Trade negotiation: ministerial conferences and working groups provide a forum for multilateral tariff and market access negotiations (Doha Round, fisheries subsidies agreement). Monitoring: the Trade Policy Review Mechanism conducts periodic reviews of member trade policies, providing transparency on compliance. Dispute settlement: the DSB (Dispute Settlement Body) hears complaints filed by member states against alleged WTO violations, with panels issuing rulings and the Appellate Body hearing appeals.
Dispute settlement was the WTO's defining innovation over GATT — rulings were binding and states could face authorized retaliation for non-compliance. The system worked reasonably well through the 2000s. The Appellate Body crisis began in 2017 when the Trump administration blocked new appointments, citing concerns that the Body had exceeded its mandate through judicial overreach. By December 2019, the Body fell below its minimum three-member quorum and ceased functioning. As of 2026, disputes can proceed through panel stage but cannot be finally resolved through appeal — leaving a legal limbo where findings are technically contestable indefinitely.
The Appellate Body crisis is not a technical malfunction — it is the institutional expression of a US strategic judgment: that rules-based trade adjudication no longer serves US interests when China is the primary user and beneficiary. China became the world's most active WTO complainant, systematically filing disputes against US and EU trade measures — winning a significant percentage and using the rulings as diplomatic leverage. The US conclusion was that the Appellate Body had become a tool that constrained US trade policy more than it constrained Chinese industrial policy.
The WTO's institutional paralysis has accelerated bilateral and plurilateral trade deal-making as the primary mechanism for managing international trade relations. RCEP (2022), CPTPP (2018 without US), and bilateral FTAs between major economies reflect the shift from multilateral to networked trade governance. The practical consequence is that the WTO's most-favored-nation (MFN) principle — equal treatment of all members — is being systematically circumvented through preferential agreements that create two-tier access to major markets.
The United States uses the WTO selectively: filing complaints against China's industrial subsidies and export controls (invoking the institution when convenient) while applying Section 301 tariffs, national security exemptions (Section 232), and the IRA's domestic content requirements outside WTO authorization (bypassing it when inconvenient). This pick-and-choose posture is legally coherent within the WTO's national security exception (Article XXI) but corrosive to the institution's authority as a rules-based framework.
China files WTO disputes as a legitimacy signal even when the Appellate Body cannot enforce them — the complaint record itself serves diplomatic purposes, demonstrating that China operates within the rules-based framework while the US does not. The EU has attempted to construct an interim appeal arbitration mechanism (MPIA) with other WTO members to preserve some dispute resolution function outside the dysfunctional Appellate Body. Developing members use the MFN principle and GSP (Generalized System of Preferences) provisions to secure preferential market access to developed-country markets.
