production should be carefully monitored and subject to systematic international on-site inspection. GROUP II CHEMICALS - REGIME II Group II Chemicals 1. Super-toxic lethal chemicals (other than those in Group I) which are presently developed, produced or stockpiled only for permitted purposes but which warrant special attention to ensure that they are not developed, produced or stockpiled for chemical weapons purposes in the future. Example: Strophantin (a glycocide for heart ailments). 2. Key precursors (other than those in Group I) used for permitted purposes but which have also been produced for chemical weapons purposes. Example: thiodiglycol. Regime II Declarations of Group II chemicals should encompass all key precursors in chemical weapons stocks as under Regime I, as well as stocks for permitted purposes and aggregate annual production of each of the Group II chemicals stating also their respective end uses. Facilities for production of Group II chemicals should be declared as under Regime I if production has been for chemical weapons purposes (key precursors) or if the production exceeds certain quantities. Elimination . Key precursors in chemical weapons stockpiles should be eliminated either through destruction or through diversion to permitted purposes. Facilities having produced key precursors for chemical weapons purposes should be eliminated through destruction or dismantling if the total production capacity exceeds what is consistent with production for permitted purposes. Production of Group II chemicals should take place at the single small-scale facility or at other especially approved facilities. The possibility of limiting production to a certain amount annually or at any one time could also be considered, in which case provisions for granting exceptions in specific cases might prove needed. To ensure that these chemicals are not developed into new types of chemical weapons or produced for chemical weapons purposes the verification needs to be stringent. Data reporting as well as systematic international on-site inspection 
**Analysis**
The text appears to be discussing the regulation and monitoring of the production and stockpiling of certain chemicals, specifically those that could be used as weapons. The focus is on ensuring that these chemicals are not used for chemical weapons purposes and that their production and stockpiling are transparent and verifiable. This suggests that the text is related to issues of security and disarmament.
