Washington launched trade investigations into 16 economies including Taiwan on Wednesday, marking a sharp turn in US economic policy that places America's most critical semiconductor supplier under the same scrutiny as China.
US Trade Representative Jamieson Greer announced the Section 301 probe less than three weeks after the Supreme Court struck down the previous administration's sweeping global tariffs. The examination targets whether these economies' "policies and practices contribute to structural excess capacity and production" in manufacturing sectors and whether they constitute "unreasonable or discriminatory" conduct.
The other 15 targeted economies are China, Japan, South Korea, the European Union, Singapore, Switzerland, Norway, Indonesia, Malaysia, Cambodia, Thailand, Vietnam, Bangladesh, Mexico, and India.
Greer stated the initiative reflects efforts to "rebuild American manufacturing and strengthen domestic supply chains." He emphasized: "In many sectors, the United States has lost substantial domestic production capacity or has fallen worryingly behind foreign competitors."
The administration characterizes foreign structural overcapacity as an obstacle to US reindustrialization. Section 301 authority, dating to the Trade Act of 1974, permits retaliatory tariffs for unfair trade practices.
The investigation presents a paradox: Washington is scrutinizing Taiwan for trade practices even as US defense and technology policy depends fundamentally on Taiwan Semiconductor Manufacturing Company. TSMC produces over 90 percent of the world's most advanced chips, including those powering American AI systems and military hardware. The company is currently building fabrication plants in Arizona, Texas, and New York under the CHIPS Act.
Consultations have been requested with all 16 governments. A public hearing is scheduled for May 5. Taipei has not yet issued a formal response to the probe.
The timing is notable. Taiwan faces intensifying military pressure from Beijing, which conducted large-scale military exercises around the island last month. The trade investigation adds economic uncertainty to an already complex security environment.
Watch what they do, not what they say. In East Asian diplomacy, the subtext is the text. Washington's decision to group Taiwan with China in a trade probe signals that semiconductor dependency, however critical to American interests, will not shield Taipei from commercial scrutiny. The investigation tests whether strategic partnership and trade enforcement can coexist—or whether one inevitably undermines the other.
