The original KORUS was born out of bilateral consultations that began at the end of 2004, when the idea of a trade agreement between the two countries had already been launched in the 1980s. An agreement was reached in April 2007, which was revised next month to reflect the demands of Democrats in Congress and signed by the parties on June 30, 2007.3 The main features of the agreement were a deadline period for the removal of most tariffs on bilateral trade, with automotive and agriculture being the most remarkable areas of liberalization; Reducing the burden imposed by The various Korean tax and regulatory policies; Third, Korea has requested changes to the rules of origin applicable to three categories of textile products that are not available in either Korea or the United States and must therefore come from other countries37. This amendment was requested, since the current ”Garnforward” rules allow a textile product to qualify for the lower tariffs of a free trade agreement than if it is made of yarns and fabrics from one of the parties to the free trade agreement. The United States supports specific rules in its trade agreements because it restricts intermediate consumption from other countries.38 The United States has agreed to expedite its process of verifying domestic and domestic availability and has expressed its willingness to change the rules of origin specific to textile and clothing products (Annex 4-A) if there is no commercial availability. This would be a positive development in terms of relaxing the strict rules on cutting-edge yarn, which hinder the most efficient methods of textile and clothing manufacturing. The agreement was ratified by the United States on October 12, 2011, with the Senate having passed it 83-15 and the House of Representatives 278-151.  It was ratified by the South Korean National Assembly on 22 November 2011 by 151 votes in, 7 against and 12 abstentions.  The agreement came into force in March 2012.  A new renegotiation took place between the end of 2017 and the end of March 2018, when an agreement was reached between the two governments. 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.
