Since 2011, the EU-South Korea trade agreement has removed tariffs on almost all products. In addition, many other barriers to the export of EU products such as automobiles, pharmaceuticals, electronics and chemicals have been removed. Many services between the EU and South Korea have also been opened to investors and commercial companies. The December 2010 agreement was a compromise between the two sides. Significant concessions have been granted to the United States with respect to auto trade: tariff reductions for Korean automobiles have been delayed by five years and U.S. cars have gained wider access to the Korean market. At the same time, negotiators agreed to set aside differences of opinion on U.S. beef exports for the time being. The trade agreement contains clear rules for the registration of trademarks in the EU and South Korea. On June 6, 2010, President Barack Obama and President Lee Myung-bak reaffirmed their commitment to the treaty and declared that they would order their governments to remove remaining obstacles to the agreement by November 2010.

The U.S. Chamber of Commerce opposed the withdrawal from the agreement.  Until October 4, 2017, the Trump administration had withdrawn from the Korus Free Trade Agreement and agreed with South Korea to renegotiate the agreement.
