In a joint statement on Oct. 22, a diverse, cross-regional group of UN member states led by Austria and including the United States expressed concern about “new technological applications, such as those related to autonomy in weapons systems.”

Several major powers are developing and, in some cases, fielding various types of autonomous combat systems, including unmanned aerial vehicles, ground vehicles, surface vessels, and undersea vessels. Many of these weapons utilize artificial intelligence to improve capabilities to identify, track, and attack enemy targets.

The joint statement follows more than eight years of inconclusive discussions among the 125 states-parties to the Convention on Certain Conventional Weapons (CCW) on the subject of lethal autonomous weapons systems.

In CCW discussions, held in Geneva, many have called for binding agreements to limit or ban these weapons systems, while the states that are building autonomy into certain weapons systems, including Russia and the United States, have resisted calls for a binding agreement and instead advocated for a less restrictive “code of conduct.” The CCW operates by consensus.

In their national statements delivered in October at the UN General Assembly First Committee, many of the signatories of the statement, including France, the United

Kingdom, and the United States, expressed support for the ongoing work of the CCW group of governmental experts on lethal autonomous weapons issues, which is chaired by Brazil. The Netherlands expressed the need for the experts group to produce “concrete results.”

The Oct. 21 joint statement indicates there is a growing concern among key states about the adverse impacts of lethal autonomous weapons systems and, as the statement suggests, growing support for action leading to the adoption of “appropriate rules and measures, such as principles, good practices, limitations and constraints,” including “through internationally agreed rules and limits.”
