In early 2011, many Members of Congress focused their attention on U.S. rules and practices governing the importation of products and components from North Korea. Their interest was stimulated by debate over the proposed South Korea-U.S. Free Trade Agreement (KORUS FTA) and the question of whether the agreement could lead to increased imports from North Korea. Some observers, particularly many opposed to the agreement, have argued that the KoreanUS FTA could increase imports from North Korea if South Korean firms re-export items made in the Kaesong Industrial Complex (KIC), a seven-year-old industrial park located in North Korea, where more than 100 South Korean manufacturers employ over 45,000 North Korean workers.
