This report provides background information on the nuclear negotiations over North Korea's nuclear weapons program. Since August 2003, negotiations over North Korea's nuclear weapons programs have involved six governments: the United States, North Korea, China, South Korea, Japan, and Russia.

At least 50 documented incidents in more than 20 countries around the world, many involving arrest or detention of North Korean diplomats, link North Korea to drug trafficking. Such events, in the context of credible, but unproven, allegations of large scale state sponsorship of drug production and trafficking, raise important issues for the United States and its allies in combating international drug trafficking. The challenge to policy makers is how to pursue an effective counter drug policy and comply with U.S. law which may require cutting off aid to North Korea while pursuing other high-priority U.S. foreign policy objectives including (1) limiting possession and production of weapons of mass destruction; (2) limiting ballistic missile production and export; (3) curbing terrorism, counterfeiting, and international crime; and (4) addressing humanitarian needs.

In October 2002, the United States confronted North Korea about its alleged clandestine uranium enrichment program. Soon after, the Agreed Framework collapsed, North Korea expelled international inspectors, and withdrew from the Nuclear Nonproliferation Treaty (NPT). U.S. intelligence officials claimed Pakistan was a key supplier of uranium enrichment technology to North Korea, and some media reports suggested that Pakistan had exchanged centrifuge enrichment technology for North Korean help in developing longer range missiles.
