Abstract This paper aims to examine the importance of co-operation for maritime security in the South Atlantic, focusing on the relationship between the national and sub-regional institutions that have leveraged this process, especially those from Brazil. For this purpose, the diagnosis addresses the debates around the contemporary roles of the navy and the importance of international co-operation for its mission accomplishment, highlighting the tasks judged as subsidiary, among them being that of maritime traffic control. The alignment of these co-operative activities with foreign policy and national defence projects can be seen through the navy’s participation in multilateral co-operation projects involving South America, particularly the Co-ordination for the South Atlantic Maritime Area (CAMAS). The research detects the existence of a particular model of a community of security practice in which national and sub-regional institutions have been generating an important maritime co-operative system, which is more stable than in other areas of co-operation in the same region.

Reputação internacional é um objeto do direito internacional cujo valor se dá pela atribuição positiva ou negativa a respeito de um Estado pelos demais ou, de outro modo, pela capacidade de um determinado Estado agir de acordo com seus compromissos, frequentemente chamada de confiabilidade. Dessa forma, os imperativos da política externa de um país são qualificadores de sua recepção pela comunidade internacional entre graus variáveis de confiança e desconfiança. Este artigo tem como finalidade a organização tipológica de modelos de reputação com base tanto na existência de característica cooperativa quanto no exercício de preponderância que alguns Estados gozam no ambiente internacional competitivo.

International reputation is a feature of international law whose value is given by other actors assigning a positive or negative rating, connected to a state's willingness and capacity to comply with its commitments - often also termed reliability. Thus, the imperatives of a country's foreign policy are the determinants of its being received by the international community with varying degrees of trust. This article establishes a typology of reputation models based on both cooperative and dominance paradigms of the reputation states enjoy in the competitive international environment.
