New technologies transform the nature of armed conflict. Most emerging technologies are aimed not to destroy the enemies’ armed forces, but to achieve political goals by inflicting minimum physical damage and the use of most of these technologies doesn’t constitute an armed conflict. New technologies include cyber, AI, drones, lethal autonomous weapons—those which don’t have an internationally agreed definition, and cannot be subject to arms control limitations due to their wide civilian commercial application. Nonetheless their development and possible use may have significant impact on national and international security. This poses a serious challenge to arms control, it is unclear how to deal with their production, rules of engagement, verification, export control, non-proliferation. The chapter summarizes the existing expert opinions and government positions on how to work out international rules of engagement on such technologies. The general purpose of the paper is to find the common arguments, acceptable for the key actors, including Russia, Europe, and US on the issues, in order to negotiate the possible agreement.
