In 2002, the group took two important steps to strengthen export control. The first was the "no-undercut" requirement, which stated that any member of the group considering making an export to another state that had already been denied an export by any other member of the group must first consult with that member state before approving the export. The second was the "catch-all" provision, which requires member states to halt all exports that could be used by importers in chemical or biological weapons programs, regardless of whether the export is on the group's control lists.[3] Delegations representing the members meet every year in Paris, France.[4]
