Some issues were treated as amendments to the original KORUS, while others, which were not included in the original, were negotiated in the form of ancillary agreements guaranteed by exchanges of letters between the parties. Amendments requested by the United States included steel export restrictions, a higher quota of U.S. cars exported to Korea, in line with U.S. emissions and safety standards instead of the uniquely Korean rules, an extension of us tariffs on imported pick-up trucks, changes to Korean drug pricing rules and new procedures for Korean customs inspections. There have also been several Korean applications that have resulted in changes in investor-state dispute settlement procedures and trade defence mechanisms, as well as rules of origin for certain textile products.

There will be no renegotiations.
