Proliferation Security Initiative (PSI)


The Proliferation Security Initiative (PSI) provides the international community with the practical means of cooperating to prevent illicit trafficking in weapons of mass destruction (WMD), their delivery systems and related materials. It aims to impede illicit WMD-related trade to and from states of proliferation concern and terrorist groups. More than 100 countries have endorsed the PSI Statement of Interdiction Principles. The core objectives of the PSI are contained in these Principles, which all participating countries publicly support to complement the objective of UNSC Resolution 1540 of helping prevent WMD proliferation.

PSI exercises

A priority for Australia, and all other PSI participants, is to maintain and refine capabilities for interdicting WMD-related trade. Countries participating in PSI activities have developed their maritime, air and ground interdiction capabilities through a program of joint training exercises in Europe, Asia and North America. These exercises are designed to: enhance operational responsiveness by testing national interdiction capacities; improve mechanisms for conducting joint interdiction operations with other countries; bridge differences in training and operational systems and allow policy experts, enforcement agents and operational personnel to learn to work together in a cooperative and collaborative manner. Australia has hosted three PSI interdiction exercises.

The future

In 2013, participating states commemorated the 10th anniversary of the establishment of the PSI. In May 2013, states gathered in Poland to mark this occasion and recommit to the fundamental principles guiding the PSI. Australia played a lead role in planning and executing this event. Australia also agreed - with the vast majority of PSI states - to commit to strengthen the PSI and where possible enhance our collective capacity on a whole-of-government basis to prevent the proliferation of WMD, their delivery systems and related material. Australia looks ahead to continued active partnership in the PSI, including to raise awareness of - and expand support for - the Initiative in the Asia-Pacific region.
