China's General Administration of Customs has implemented strict export requirements for watermelons from Vietnam to ensure food safety and prevent pest transmission. Exporting farms must register with both Vietnamese and Chinese agencies, adhere to good agricultural practices, and establish a traceability system. Watermelons must be free from certain living plant quarantine agents and contaminants. During export, watermelons undergo sampling and inspection, and if the requirements are not met, the shipment can be rejected or destroyed. This measure aims to protect China's agricultural health and consumer safety, holding exporting countries accountable for meeting these standards.
