The Clinton Administration signed an agreement with North Korea on October 21, 1994, detailing steps to end the crisis caused by North Korea's nuclear program and pledging to "move toward full normalization of political and economic relations." Many details of the accord have not been disclosed, including the precise mechanisms to be used to provide light water nuclear reactors and annual shipments of U.S. heavy oil to North Korea, and a clear process to be followed in normalizing political and economic relations.
