According to the website of the Ministry of Public Security, in 2024, in accordance with the unified deployment of the Ministry of Public Security, the public security organs of Shanghai, Jiangsu, Zhejiang, Anhui and other provinces and cities in the Yangtze River Delta will carry out the "Kunlun" regional battle No.1 action, crack down severely on illegal disposal of solid waste and other environmental pollution crimes in accordance with the law, and achieve significant results. Throughout the year, public security organs in four provinces and cities in the Yangtze River Delta region filed and investigated over 450 cases of environmental pollution crimes. The public security organs insist on placing the maintenance of the ecological security of the Yangtze River in a prominent position, closely monitoring criminal activities such as excessive discharge of pollutants and illegal dumping of toxic and harmful substances, and severely investigating and punishing malignant cases that endanger the ecological security of the Yangtze River. The Ministry of Public Security has conducted centralized supervision and handling of 15 major cases of environmental pollution, guiding relevant localities to investigate and solve a number of criminal cases that have a negative impact, effectively playing a role in criminal crackdown and deterrence. In response to the illegal transfer, dumping, and disposal of solid waste across provinces, the public security organs have deepened regional police cooperation, strengthened coordination and cooperation, adhered to the full link, full element, and full chain crackdown, and solved more than 40 cross regional criminal cases, and concentrated on cracking down on a number of mobile criminal gangs. In response to various crimes that endanger food security, the public security organs have adopted a "zero tolerance" attitude to crack down on illegal transfer and dumping of solid waste in rural areas, and have solved more than 20 cases of illegal occupation of agricultural land and other crimes that damage farmland, ensuring national food security. At the same time, the public security organs pay more attention to departmental linkage, closely combining with the special action of cracking down on illegal and criminal activities related to hazardous waste environment jointly carried out with the ecological environment department and the procuratorial organs, and jointly promoting the crackdown and rectification work, constantly consolidating the work force. Pay more attention to typical demonstrations, summarize and promote the experience and practices of Shanghai Qingpu's joint execution and governance, Jiangsu Changzhou's crackdown on similar cases, Zhejiang Huzhou's ecological policing, and Anhui Hefei's departmental cooperation, and fully play a leading role. We will pay more attention to capacity building, with the establishment and improvement of a new police operation model of "professional+mechanism+big data" as the driving force, and carry out capacity enhancement projects in depth. We will focus on exploring the potential of technological means and big data applications, and promote the improvement of the quality and efficiency of the fight against environmental pollution crimes. Next, the public security organs will always maintain a high-pressure deterrence situation of cracking down on environmental pollution crimes in accordance with the law, further focusing on key industries, key behaviors, key links, etc., constantly innovating precision strike, deep strike, scale strike, and linkage strike strategies and methods, fully fighting the overall battle, tough battle, and coordinated battle, resolutely safeguarding the safety bottom line of building a beautiful China, and escorting high-quality development in the Yangtze River Delta region.
