U.S. Trade Representative Jamieson Greer said the tariff increases announced by President Donald Trump last week are unlikely to be rolled back, calling the newly set rates "pretty much set" during an interview broadcast Sunday on CBS’s "Face the Nation." The executive order signed earlier in the week imposes duties of 35% on many Canadian goods, 50% on Brazilian shipments, 25% on imports from India, 20% on those from Taiwan and 39% on Swiss products, all due to take effect on Aug. 7. Greer nevertheless indicated that a separate rise on Chinese imports scheduled for Aug. 12 could slip, remarking, "I don’t think anyone wants to see those tariffs snap back to 84%." Greer said recent discussions with Beijing have been "very positive," centering on the flow of rare-earth magnets and related supply chains, and claimed talks are "about halfway" to restoring pre-tariff trade conditions. He also defended the administration’s use of steep levies—particularly the 50% charge on Brazil—as a legitimate geopolitical tool.
