The Office of the US Trade Representative (USTR) on March 11 launched investigations under Section 301 of the Trade Act of 1974 against 16 major trade partners, including China, the European Union, South Korea, Japan, India, and Taiwan. Taiwan’s government said the move was anticipated after the recent Supreme Court of the US ruling that struck down tariffs imposed under the International Emergency Economic Powers Act (IEEPA), prompting Washington to seek alternative legal mechanisms to maintain its tariff framework.
