Last 12 months dozens of nations proposed or launched new tariffs on metal imports. Most aimed the measures at China, which they accused of flooding worldwide markets with low cost steel.

Because the president flew to the Tremendous Bowl in New Orleans, he informed reporters on Air Drive One which he would announce new tariffs of 25% on all aluminium and metal imports into America. On February tenth the levies duly arrived.
