The United States is set to reimpose sanctions on Iran starting tomorrow, August 6th, and that's already taken a toll on South Korea's trade with Iran.<br />Data from the Korea International Trade association show exports to Iran declined in the first half of this year by 15-point-4 percent compared to the same time last year.<br />Those exports from January to June were still worth over 1-point-7 billion dollars.<br />But they're going to decline further because secondary sanctions will apply to countries that continue to trade with Iran.<br />The sanctions coming back on Monday cover cars, metals and minerals.<br />Another big blow could come in November when sanctions are reimposed on oil.<br />South Korea buys a lot of crude oil from Iran -- around 3-and-a-half billion dollars' worth so far this year.<br />Seoul is currently asking the U.S. to for an exemption from the oil sanctions, something it was granted under the Obama administration. <br />
