Ecuador [Original: Spanish] [28 July 2017] Ecuador considers that security in international relations must be based on trust and respect among States. The continuing revelations about massive and indiscriminate systems of espionage that are being used to monitor the communications of all citizens all over the world, as well as the use of information and communications technologies in a manner that violates international law, infringe the principles of respect for sovereignty and non -interference in the internal affairs of States.
