Number: RS21391 Title: North Koreas Nuclear Weapons: Latest Developments Authors: Sharon A. Squassoni, Foreign Affairs, Defense, and Trade Division Abstract: On October 9, 2006, North Korea conducted a nuclear test, with a yield of under 1 kiloton (vice the anticipated 4-kiloton yield) . The United States and other countries condemned the test and the U.N. Security Council passed Resolution 1718 on October 14, which requires North Korea to refrain from nuclear or missile tests, rejoin the Nuclear Nonproliferation Treaty (NPT), and dismantle its WMD programs. The test is the latest provocative act of many since 2002, when North Korea ended an eight-year freeze on its plutonium production program, expelled international inspectors and restarted facilities. North Korea may now have enough Pu for eight to ten weapons. On February 13, 2007, North Korea reached an agreement with other members of the Six- Party talks to begin the initial phase (60 days) of implementing the Joint Statement from September 2005 on denuclearization. Key components include halting production at Yongbyon and delivery of heavy fuel oil. Many other aspects are yet to be decided. Pages: 6 Date: March 13, 2007
