老川是一直反对unfair trade。所以他上台之后就针对铝/钢进口的合理性开始了联邦调查。
Since Mr Trump announced parallel national security investigations into imports of the two metals (Aluminum and Steel) in April and proclaimed there were tough measures to come, imports of both have surged.
In a letter in September to Wilbur Ross, commerce secretary, urging him to speed up the investigations, Ohio senators Sherrod Brown, a Democrat, and Rob Portman, a Republican who served as US trade representative in the administration of George W Bush, complained that “the delay in the Section 232 investigation into steel imports” was causing a “corresponding surge of steel imports entering the US market”.
所以万事开头难，什么事情踏入正规都要有一个过程，也许是一两年的过程。
