ABSTRACT
The relationship between diplomacy and security is complex and evolving. States generally also face entirely novel and far-reaching threats from, for example, maritime fraud, international economic fraud, narcotics groups and transnationally organised crime. Post-war international security within the UN framework was intended to be based on the collective security. The UN Charter envisaged collective action to forestall or limit the action of a potential aggressor, through military and other measures. Thus, the UN Charter concept of security was one of states acting in concert to control or limit force. The implementation of preventive diplomacy coexists in an increasingly competitive international world. Its rivals include regional organisations, conflict resolution organisations. Apart from preventive diplomacy and peace-enforcement approaches to security in the international system, a further important dimension of internationally derived security is the development of tacit and formal rules. Overall, the security threats faced by modern states have become increasingly diverse and continue to pose additional, complex challenges for diplomacy.
