Trump Administration Launches New Trade Probes

Investigations target Mexico, China, and the EU over alleged unfair trade practices

Mar. 12, 2026 at 12:40am

The Trump administration has initiated a series of new Section 301 trade investigations into major U.S. trading partners, including Mexico, China, and the European Union. The move signals an escalation of the administration's trade enforcement strategy and could lead to further tariffs and economic tensions.

Why it matters

These investigations could have far-reaching implications for global trade relations and supply chains, as any resulting tariffs or retaliatory measures could disrupt hundreds of billions of dollars in annual trade. The outcome could also shape the direction of U.S. trade policy in the coming years.

The details

The Section 301 investigations will examine alleged unfair trade practices by the targeted countries, such as intellectual property violations, market access barriers, digital services taxes, and agricultural subsidies. The administration has indicated that additional trading partners may also be investigated based on ongoing trade disputes.
