Multilateral Nonproliferation (Export Control) Regimes and Arrangements are voluntary and nonbinding arrangement of major supplier countries, aiming to prevent the proliferation of weapons of mass destruction (WMD) and their delivery means, related equipments and technology.
There are four multilateral export control regimes (the U.S. is a member of each): the Nuclear Suppliers Group (NSG); the Australia Group (AG); the Missile Technology Control Regime (MTCR); and the Wassenaar Arrangement (WA). The NSG contributes to the nonproliferation of nuclear weapons, the AG aims to minimize the risk of assisting proliferation of biological and chemical weapons, MTCR works toward nonproliferation of unmanned delivery systems capable of delivering WMD, and the WA promotes transparency and responsibility in transfer of both conventional weapons and sensitive dual-use goods and technology. In each regime, controlled items are specified in a control list and include goods (equipment, materials etc.), software and technologies.
In addition, Security Council resolution 1540 (2004) requires all States to "take and enforce effective measures to establish domestic controls to prevent the proliferation of nuclear, chemical, or biological weapons and their means of delivery, including by establishing appropriate controls over related materials and to this end shall: establish, develop, review and maintain appropriate effective national export and trans-shipment controls over such items, including appropriate laws and regulations to control export, transit, trans-shipment and re-export ..."
