This chapter analyses the European Union security policy regarding the Asia Pacific, in the context of current trends in international security. Section one explains why the EU regards specific international security trends as important to Europe and the world and why, consequently, EU foreign and security policy-makers assume they can also influence the management of security in the Asia-Pacific. The tendency to develop regional initiatives for the co-management of security issues and the progression of the non-proliferation of nuclear and mass destruction armaments are among the trends identified. In section two, the security culture of European and Asia-Pacific nations is examined, to develop a good knowledge basis for assessing the likelihood of meaningful dialogue on security between the EU and Asia-Pacific nations. In the third section, the present state of the CSDP, common security and defence policy, is analysed in depth, to assess the likelihood of the EU becoming further involved in the Asia-Pacific security process, as a united block of countries. In the fourth and concluding section, the state of current security initiatives in the Asia-Pacific region and the future role of the EU in those initiatives are analysed.
