The Role of the Union of South American Nations in the Maintenance of International and Regional Peace and Security

The Chapter VIII of the United Nations Charter which is devoted exclusively to the regional arrangements is an essential factor in strengthening and expanding the role of regional organizations, especially in the maintenance of peace and security after the creation of the United Nations, In a way that one of the established and common principles of such organizations, as stipulated in the Article 1(1) of the Charter, is to help the United Nations in maintaining international peace and security which is interconnected with regional peace and security. Due to the capacity of regional organizations to maintain international and regional peace and security, which has been emphasized in the Article 52(3) of the Charter and Security Council’s resolutions, studying the role which could be played by one of the newly created institutions in the Latin America, i.e. the Union of South American Nations, indicates that it has significant influence on the maintenance of international and regional peace andsecurity. This Organization by highlighting confidence and security-building measures, instead of adopting an interventionist approach and coercive measures, seeks to strengthen the positive concept of peace.
