"The Assembly is concerned that the phenomenon of systematic influencing of public opinion, in particular before elections, has reached an unprecedented scale and that it is often associated with foreign interference, whether by state or non-state actors. It recalls that such interference by a state in another state’s internal affairs contravenes the well-established international legal principle of non-intervention and that States have a duty to investigate and hold to account any non-State actors that interfere in the democratic processes in other states."
