On the occasion of the Geneva Preparatory Meeting of the Conference of States Parties of the ATT, the GCSP and SIPRI jointly hosted a side event dedicated to the provisions of the Treaty regarding International Cooperation and Assistance (art. 15 and 16). This offered an opportunity to share the experience gained by the ATT Network as a multi-stakeholder platform that allowed information sharing and capacity building and could inspire the work of the future ATT Secretariat. Other panelists from Germany, Jamaica, Ghana, the Philippines and Sweden as well as UNIDIR discussed existing or possible contributions by States Parties or international organizations to coordinated cooperation and assistance for implementation of the Treaty in response to the needs of States and taking into consideration the role of civil society.
