As it is defined in Article 41, the Council can call for “ the suspension of all or part of the economic relations and of rail, sea, air, postal, telegraphic, radio, and other means of communication” under the circumstances of an international dispute or conflict. However, according to Article 42 “If the Security Council considers that measures provided by Article 41 would be inadequate or have proved to be inadequate, it may take what steps are seen as necessary by air, sea, or land forces in order to maintain or restore international peace and security. Such actions may include demonstrations, blockade, and other operations by air, sea, or land forces of Members of the United Nations. Therefore, according to Article 42, the Security Council can authorize the use of armed force in the international system.
