Under Chapter VII of the Charter, the Security Council can take enforcement measures to maintain or restore international peace and security. Such measures range from economic and/or other sanctions not involving the use of armed force to international military action.
The use of mandatory sanctions is intended to apply pressure on a State or entity to comply with the objectives set by the Security Council without resorting to the use of force. Sanctions thus offer the Security Council an important instrument to enforce its decisions. The universal character of the United Nations makes it an especially appropriate body to establish and monitor such measures.
