There were three changes made at the San Francisco Conference regarding the regional groupings or agencies. First, a provision stressing the desirability of using regional arrangements and agencies for the peaceful settlement was inserted. Second, the requirement of Security Council authorization for enforcement action under regional arrangement were waived in the case of measures taken against an enemy state under Article 107 of the Charter or under “regional arrangements directed against the renewal of aggressive policy” by any such state. Third, by the terms of Article 51 of the Charter, “the inherent right of individual or collective self-defence if an armed attack occurs against a Member of the United Nations” was safeguarded. All three statements are correct.
