South Korean officials won a permanent exemption from steel tariffs in March as part of an updated free trade agreement with the U.S. But in exchange, South Korea had to reduce its steel exports to the U.S. by about 30 percent, Similar quotas could be imposed on other countries as part of a final deal. Japan never got a break from the tariffs, so Japanese exporters have been subject to the levies since late March. That was a source of some friction when Trump hosted Japanese Prime Minister Shinzo Abe at Mar-a-Lago two weeks ago. The EU had threatened to retaliate if the steel and aluminum tariffs took effect, by imposing levies of its own on politically sensitive American exports. Potential targets include Harley Davidson motorcycles, from the home state of House Speaker Paul Ryan, and Kentucky bourbon, which could get the attention of Senate Majority Leader Mitch McConnell, R-Ky.
