The WTO's Last Stand: Can Trade Rules Survive Trump's Tariff War?

The WTO Ministerial Conference in Cameroon is meeting as the US unilateral tariff regime threatens the entire rules-based trading system. Here is what is at stake.

The 14th World Trade Organisation Ministerial Conference, convening in Yaoundé, Cameroon from March 26-29, 2026, has been described by trade lawyers and policy analysts as the most consequential WTO meeting since the organization's founding in 1995. This is not primarily because of what the conference will formally decide — the agreed deliverables are relatively modest. It is consequential because of what it represents: the multilateral trading system being asked to maintain its relevance and institutional authority in a world where its most powerful founding member has effectively opted out of its core disciplines.

The United States under the Trump administration has launched tariff investigations targeting the UK, EU, and Canada — its closest allies — under national security provisions that the WTO's dispute settlement mechanism has repeatedly found inconsistent with WTO obligations. The administration's response to these rulings has been to ignore them, continuing to apply tariffs while the appellate process that would normally enforce compliance remains non-functional due to US blocking of new appellate body appointments.

From a legal standpoint, this leaves other WTO members in an awkward position. They can sue the US and win — and they have. But winning a WTO dispute without the ability to enforce the ruling is an expensive exercise in proving a point that the defendant does not acknowledge.

The EU has arrived in Yaoundé with a package of defensive proposals designed to maintain at least the form of multilateral disciplines even in the current dysfunctional environment. These include a reformed dispute settlement mechanism that does not depend on appellate body functionality, enhanced plurilateral agreements on specific trade topics among willing members, and strengthened WTO agricultural rules that would address the subsidy practices causing the most market distortion.

Whether these proposals can generate the consensus needed to progress — with the US likely to oppose, China ambivalent, and developing countries divided — is the defining test of the WTO's continued operational relevance.
