In addition, most U.S. cars are exempt from Korea`s stricter CO2 emission requirements. To do this, the cap on green credits that U.S. manufacturers can use to pay for the increase in CO2 emissions will be raised to address the gap between U.S. and Korean emission standards25. As with the increase in the quota for cars that meet U.S. safety standards, this change is expected to have minimal impact on trade, given the low level of U.S. exports to Korea. On October 12, 2011, the U.S. Congress approved the U.S.-Korea Free Trade Agreement. On October 21, 2011, the President of the United States signed an agreement on the implementation of the agreement.
On November 22, 2011, the Korean National Assembly approved the free trade agreement between the United States and Korea. The U.S.-Korea Free Trade Agreement came into force on March 15, 2012. On September 2, 2017, President Trump said he would agree if he would soon begin the process of withdrawing from the agreement. Trump has said he consults with his top advisers, some of whom have supported the withdrawal and that some of them – including Gary Cohn, President Trump`s top economic adviser – have not done so. The U.S. Chamber of Commerce objected to the agreement`s exit.  On October 4, 2017, the Trump administration withdrew from consideration of a total withdrawal from the KORUS free trade agreement and instead agreed with South Korea to renegotiate the agreement.  The U.S.-Korea Free Trade Agreement (KORUS) came into force on March 15, 2012. On the day of its implementation, nearly 80% of U.S. exports of industrial goods to Korea were exempt from tariffs, including aerospace equipment, agricultural equipment, auto parts, construction products, chemicals, consumer products, electrical equipment, travel goods, paper products, scientific equipment and transportation and transportation equipment. Other benefits of the free trade agreement include strengthening the protection and enforcement of intellectual property rights in Korea and increasing access to the $580 billion market for highly competitive U.S. companies.
