The US President Donald Trump's administration is launching a wave of tariff-related investigations into key trade partners, including the European Union, Mexico, and China, each of which ranks among the top five sources of U.S. imports. Singapore, Switzerland, Indonesia, Malaysia, Cambodia, Thailand, Korea, Vietnam, Taiwan, Bangladesh, Japan and India will also be the subject of investigations under the trade statute known as Section 301. The Office of U., U.K. Trade Representative Jamieson Greer expects these investigations to uncover a variety of unfair trading practices. The U.N. has also announced plans to launch an investigation into the import of goods made with “forced labor” in a second announcement set for later this week. Currently, the United States has a blanket 10% tariff in place on all trading partners following a Supreme Court ruling that exceeded his presidential authority when he imposed rapid-fire tariffs on scores of countries.
