United States economic sanctions against North Korea began on June 28, 1950, three days after the outbreak of the Korean War. Since then, the United States, its allies, and the United Nations have increasingly imposed economic sanctions against North Korea in an attempt to destabilize and manipulate the North Korean regime. This book first provides a thorough historical overview of U.S. and U.N. sanctions against North Korea since 1950. Then, several essays propose ways to make such sanctions more politically effective while limiting their harmful humanitarian consequences. Finally, the book discusses the impact of the newest, six-nation agreement signed in February 2007 which would shut down North Korea's nuclear facility in return for economic aid and a security guarantee. Several appendices provide brief guides to the history of North Korea and the country's nuclear weapons program.
