As of 2017, the CCW has failed to achieve consensus to open negotiations on adding a compliance mechanism to help ensure parties honor their commitments, as well as negotiations on banning oversized-caliber bullets (5.56 or smaller). China and Russia have opposed restrictions on anti-vehicle mines, such as a requirement that such mines self-deactivate.[15] In the 2010s the CCW opened talks on restricting lethal autonomous weapons.[16]
