The Wassenaar Arrangement on Export Controls for Conventional Arms and Dual-Use Goods and Technologies was established in 1996 as the successor to the Cold War-era COCOM regime. Headquartered in Vienna, it brings together participating states that agree to maintain national export controls on items appearing on two common lists: the Munitions List and the List of Dual-Use Goods and Technologies (which includes a Sensitive List and Very Sensitive List).
The Arrangement is not a treaty and creates no binding international legal obligation. Instead, participating states commit politically to:
- Apply export controls to all items on the agreed control lists through national legislation.
- Exchange information on transfers and denials of listed items to non-participants, helping prevent destabilizing accumulations of arms.
- Make licensing decisions according to national discretion, guided by shared criteria.
Decisions are taken by consensus at the annual Plenary, typically held in December, which approves updates to the control lists. A Secretariat in Vienna supports the work, and expert groups (the General Working Group, Experts Group, and Licensing and Enforcement Officers Meeting) handle technical revisions.
Controlled items range from battle tanks and combat aircraft to specialized materials, electronics, sensors, navigation equipment, and certain cybersecurity tools. A 2013 update added controls on intrusion software and IP network surveillance systems, which generated significant debate among industry and civil-society groups about the scope of cybersecurity export controls.
The Arrangement is one of four major multilateral export control regimes, alongside the Nuclear Suppliers Group, the Missile Technology Control Regime, and the Australia Group. Critics note its limitations: key arms producers such as China are not participants, enforcement varies widely by state, and the consensus rule can slow responses to emerging technologies. Nonetheless, Wassenaar control lists shape national export regimes well beyond its membership, including in the EU dual-use regulation.
Example
In 2013, the Wassenaar Arrangement Plenary added "intrusion software" and IP network surveillance systems to its dual-use control list, prompting the United States to propose (and later withdraw) controversial implementing rules in 2015.
Frequently asked questions
No. It is a politically binding voluntary regime; obligations are implemented through each participating state's national export control laws rather than through international treaty law.
