The United States has initiated a new trade investigation targeting several major partners, including Bangladesh and India. The move follows a Supreme Court decision last month that struck down a key part of President Donald Trump’s tariff policy. US Trade Representative Jamison Greer said the probe, launched under Section 301, aims to assess unfair trade practices and could lead to new tariffs on countries such as China, the European Union, Japan, South Korea, and Mexico by mid-summer.

The investigation also covers Vietnam, Thailand, Malaysia, Cambodia, Singapore, Indonesia, Switzerland, and Norway, but excludes Canada, the US’s second-largest trading partner. The Supreme Court recently ruled that Trump’s previous global tariffs, imposed last April, were illegal because the president exceeded his authority under the International Emergency Economic Powers Act. The court reaffirmed that only Congress can authorize such extraordinary powers.

Following the ruling, Trump reimposed a 10 percent global tariff and threatened to raise it to 15 percent. The new investigation gives his administration leverage to pressure trade partners ahead of upcoming talks with China in Paris and a possible Trump–Xi meeting in Beijing later this month.
