Many of the 120 states that are part of the Convention on Conventional Weapons (CCW) are participating in the 2015 CCW meeting of experts, which is chaired by Germany’s Ambassador Michael Biontino who has enlisted “friends of the chair” from Albania, Chile, Hungary, Finland, Sierra Leone, South Korea, Sri Lanka, and Switzerland to chair thematic sessions on a range of technical, legal, and overarching issues including ethics and human rights.

The session proved to be one of the most engaging this far at the 2015 experts meeting. The UK made a detailed intervention that included the statement that it “does not believe there would be any utility in a fully autonomous weapon system.” France said it has no plans for autonomous weapons that deploy fire, it relies entirely on humans for fire decisions.

Three states that have explicitly endorsed the call for a preemptive ban on lethal autonomous weapons systems have reiterated that goal at this meeting (Cuba, Ecuador, and Pakistan), while Sri Lanka said a prohibition must be considered. There have been numerous references to the CCW’s 1995 protocol banning blinding lasers, which preemptively banned the weapon before it was ever fielded or used.
