WASHINGTON, June 2 (Reuters) – U.S. Trade Representative Jamieson ‌Greer said on ‌Tuesday that the Trump administration will ​release the results of several Section 301 trade investigations over the coming ‌weeks, ⁠adding that proposed 25% tariffs are “quite nuanced” ⁠due to broad exclusions for beef, coffee, metals, ​energy and ​other ​goods.

Greer, speaking ‌on CNBC’s Squawk Box program, said that the administration has had very good results from its tariff ‌program in ​boosting U.S. exports. ​He ​said substantial tariffs ‌were needed to ​correct persistent ​unfair trade practices around the world and ​a “giant” ‌U.S. trade deficit.
