Following Kim Il Sung's November 1980 order to develop biological and chemical weapons, North Korea accelerated its biological weapons development by deploying special personnel to the No. 25 Factory, the Microbiological Institute (미생물연구소), and the Medical Institute (의학연구소). The No. 25 Factory is reportedly a site for biological weapons production. According to a 1992 report by South Korea's Agency for National Security Planning (국가안전기획부), North Korea produces 13 types of BW agents, such as bacillus anthracis (anthrax), cholera, typhoid bacillus and plague bacteria at the No. 25 Factory, the Party Central Biological Research Institute (당중앙생물연구소), and the Preventive Military Medical Unit (예방군사의료부대). The report says that these BW agents are sent to the Munch'ŏn Agar Factory (문천한천공장) for weaponization.
