Recently, the Discipline Inspection and Supervision Commission of Xifeng County, Guizhou Province, issued a disciplinary inspection and supervision proposal to the County Development and Reform Bureau in response to the long-standing issue of Peng, the former chairman of Jinsui Grain and Oil Purchase and Sales Company, illegally distributing subsidies. The proposal urged the bureau to rectify the problems of lax daily supervision and inadequate management system and mechanism of its subordinate state-owned enterprises, and establish and improve financial management, approval and other systems. This is a concrete manifestation of Guizhou's continuous deepening of the special rectification of corruption in the field of grain purchase and sales, and the promotion of a sound long-term mechanism for managing grain. Since the launch of the special rectification, the disciplinary inspection and supervision organs at all levels in Guizhou Province have concentrated on solving a number of prominent problems in the field of grain purchase and sales, and have seriously investigated and dealt with a number of typical cases of violations, discipline and law in the field of grain. Focusing on the main responsibilities of local party committees and governments in grain purchase and sales, the supervisory responsibilities of industry supervisory departments, and the implementation responsibilities of state-owned grain enterprise policies, a number of institutional mechanisms have been established and improved to promote the efficiency of governance in the field of grain purchase and sales. Analyze and summarize the characteristics and laws of violations of discipline and law in grain related cases, and continue to tighten the responsibilities of all parties involved in grain purchase and sales. Wu Qingchun, a former department level cadre of the Guizhou Provincial Grain and Material Reserve Bureau, has been expelled from the Party; Since the 20th National Congress of the Communist Party of China, the disciplinary inspection and supervision organs of Guizhou Province have adhered to the investigation and handling of cases as an important means of deepening special rectification work, closely monitoring local party committees and governments, supervisory departments and state-owned grain enterprises, and strengthening supervision and inspection around responsibility, work style, and corruption issues. At the same time as investigating cases, analyze and summarize the characteristics and laws of violations of discipline and law in grain related cases. Officials from the Guizhou Provincial Commission for Discipline Inspection and Supervision told reporters that based on the investigation and handling of cases, there have been frequent violations of discipline and law in the fields of grain reserves and purchase and sales. Ultimately, it is due to the leniency of local authorities, grain regulatory departments, and reserve grain management enterprises in managing the Party, neglecting supervision and management, and abandoning their main responsibilities and businesses. Continuously reminding, urging, and promoting party committees and governments at all levels to effectively assume the main responsibility for food purchase and sales safety - self inspection, self correction, and supervision inspections throughout the province have found that there is a gap in the fulfillment of main responsibilities by some local party committees and governments, and the coordinated promotion of solving problems in the field of food purchase and sales is not strong enough. Some fail to implement the decisions and deployments of superiors in a timely manner; Some reserve tasks are not fully implemented; Some warehousing facilities have shortcomings. The Guizhou Provincial Commission for Discipline Inspection and Supervision has promoted the issuance of the "Assessment Measures for the Implementation of the Responsibility System for Cultivated Land Protection and Food Security by the Party Committees and Governments of Guizhou Province and Cities (Prefectures)", urging strict and practical implementation of the provincial assessment of the responsibility system for food security in cities (prefectures), further strengthening the implementation of the main responsibility of local Party committees and governments for food security, and promoting the establishment of more than 30 regulations and systems around the main responsibility of local Party committees and governments for food purchase and sales. Continuously consolidating the regulatory responsibilities of grain regulatory authorities - In practice, there have been instances where regulatory authorities such as development and reform, finance, market supervision, and grain have not fulfilled their regulatory responsibilities effectively enough. Some have not formed a normalized law enforcement inspection mechanism, and the supervision and guidance of grassroots state-owned grain enterprises are not strong enough; Some regulatory authorities lack sufficient cooperation and cooperation, leading to regulatory blind spots; In some places, the allocation and use of grain fiscal funds are not timely.
