# White House launching unfair trade investigations, rebuilding tariff pressure

The White House is launching new investigations into alleged unfair trade practices involving a number of countries, weeks after President Trump imposed a 10 percent tariff on goods not covered under current exemptions.

U.S. Trade Representative Jamieson Greer told reporters during a press call Wednesday that the Trump administration is opening probes into the tax policies and practices of China, the European Union, Singapore, Switzerland, Norway, Indonesia, Malaysia, Cambodia, Thailand, South Korea, Taiwan, Bangladesh, Mexico, Japan and India, according to The Hill’s sister network NewsNation.

“We expect that this investigation will uncover a variety of unfair trading practices related to excess capacity and production in manufacturing,” Greer said.

The administration is launching the investigations under Section 301 of the Trade Act of 1974, which allows the president to implement tariffs in response to “discriminatory” trade practices by other countries.

Trump implemented the 10 percent levies after the Supreme Court struck down a majority of his import taxes imposed under the International Emergency Economic Powers Act of 1977 last month. The latest tariffs were imposed under Section 122 of the Trade Act, which allows the president to hike import taxes to address “large and serious United States balance-of-payments deficits.”

The 10 percent tariffs are set to expire July 24. Greer said Wednesday that the administration wants to conclude its probe into foreign trading practices by then.

The trade ambassador said his office will begin accepting public comments on March 17, with a deadline of April 15 to submit. The administration will then hold a public hearing on or around May 5.

“We don’t want to prejudge the outcome of these investigations,” he said.

Also during the call, Greer announced another Section 301 investigation related to a ban on imports of goods made via forced labor. He expects that probe to cover roughly 66 countries.

“This is not about domestic conditions of particular countries,” Greer added. “It is really about whether countries have implemented external facing law to prohibit the imports of goods using forced labor.”
