U.S. Commerce Secretary Wilbur Ross has suggested it's insulting to pick a trade fight with South Korea while North Korea is building up its nuclear arsenal. <br /> In an editorial,... the Washington Post reported Ross' proposal says 'good relations with allies like Seoul and Tokyo are especially crucial to U.S.-led efforts' aimed at countering the regime's nuclear and missile ambitions. <br />Ross proposed cures are 'likely to be worse than any disease' as tariffs and quotas generally prove counterproductive.<br />The report comes shortly after the Trump administration released a new document on steel imports,... calling for new tariffs and quotas to protect U.S. industry. <br />
