The Donald Trump administration in the United States has launched new "unfair trade practice" investigations into 16 key trading partners, including India, China and Bangladesh, in a move to restore tariff pressure after they were struck down by the US Supreme Court as illegal last month. 

US Trade Representative (USTR) Jamieson Greer said that the "Section 301" unfair trade practices investigation could lead to new tariffs imposed against China, the European Union, India, Japan, South Korea and Mexico by this summer.

Other trading partners subject to the excess capacity probe include Taiwan, Vietnam, Thailand, Malaysia, Cambodia, Singapore, Indonesia, Bangladesh, Switzerland and Norway.  Canada, the second-largest US trading partner, was not mentioned as a target of the probe.
