The resolution also addresses the question of "related materials". Its definition includes chemicals and equipment covered by multilateral arrangements and national control lists such as the Australia Group, the Proliferation Security Initiative and the EU’s strategy against the proliferation of WMD, and is thus much broader than the three schedules of chemicals in the Annex of the CWC. In addition non-state actors can already cause serious damage with amounts that are far below those that are considered militarily significant and states should consider this in their actions to counteract the preparation or use of chemical weapons by those actors.[18]
