On the 25th, ahead of the 36th National Land Day, the Ministry of Public Security published four representative cases as part of a nationwide, problem‑oriented criminal campaign against illegal occupation of agricultural land. Targets include illegal conversion of cropland and forestland for construction, sand dredging, mining and dumping of solid waste; building housing disguised as agricultural facilities or agricultural parks (large 'greenhouse' housing); unapproved construction, occupying more than approved, and parcel‑splitting to evade oversight. The ministry said police have timely cracked a number of related criminal cases. The drive is framed as protecting national food security and ecological safety.(金十数据)
