China is heavily modernising its border security deploying an array of A I – powered biosecurity systems and Smart Customs networks to safeguard national borders and streamline international supply chains.
The Asian country is highly reinforcing its border biosecurity system through the use of artificial intelligence and big data with the country’s customs authorities actively working to create a “space - air - land” monitoring systems to protect borders against biological threats.
Since 1 May 2026, an official list of dangerous alien species subject to strict control has been operating at the borders, continuing the operations started at the beginning of this year when China’s customs authorities have been carrying out a three - year campaign to prevent the penetration of pests.
According to Xinhua News Agency, a strategic document was prepared by the PRC’s General Administration of Customs (AGA), the ministry - level agency under the State Council regulating cross - border trade, tariff, collection, and border health checks along with five other agencies.
The Deputy Director of the AGA’s animal and plant quarantine department Liu Jian said that an intelligent exotic pest identification model has been implemented, consisting in a system that recongnizes more than 1.000 species of weed insects and plants with more than 50 percent accuracy, and thanks to the unification of inter - agency databases, an instantaneous verification of 12 categories of agricultural products has been organised.
In addition more than 120.000 electronic applications have been processed, alongside automated sampling systems and smart detectors make it possible to maintain a high level of security without showing down foreign trade operations.
The rapid integration of advanced technology has transformed China’s border management across several key domains:
• Non - Intrusive Inspection (NII): AI - based image analysis systems are equipped on hundreds of scanning devices. These algorithms automatically detect concealed contraband, drugs, endangered species, and invasive pests or exotic pests in cargo.
• Space - Air Ground Monitoring: To control plant pests, diseases, and cross – border contamination, authorities utilize an integrated network of satellites, drones, and chip -level sensors. This allows for low - altitude, high - precision detection of environmental or biological threats.
• Humanoid Robot Patrols: At key land crossings such as those along the Vietnam border, authorities have deployed AI - driven humanoid robots like the Walker S2 to assist with crowd management, guide vehicles, check container seals, and monitor passenger flow.
• Big Data Risk Screening: Customs leverage intelligent targeting models across hundreds of air, land, and sea ports to automatically assess commodity origins and value, raising the interception rate of prohibited agricultural products and biosecurity threats significantly higher than manual targeting.
In Eastern China’s Zhejiang province, customs officials use smart glasses with AI functionality. The devices instantly recognize the characteristics of goods and translate foreign labels, reducing cargo clearance time by 39 percent.
At the port of Tianjin, a provincial - level direct administered municipality located on the shore of the Bohai Sea, specialized digital complexes perform comprehensive verification of mineral raw materials in a matter of minutes were implemented.
In Zhangjiagang, a county - level - city under the administration of Suzhou in Jiangsu province, Customs applied AI for the control of wood products. The systems recognize 145 types of wood, more than 150 species of weed seeds and 80 species of insects.
In Nanjing, capital of China’s eastern Jiangsu province, roughly 300 km up to the Yangtze River, customs using AI can detect live exogenous parasites in international postal shipments.
China also develops cooperation with neighbouring countries. Based on AI and big data, a cross - border intelligent monitoring system is being created. The parties exchange databases on biological species, conduct joint field monitoring and risk analysis.
A collaboration with neighbouring countries like Vietnam aims to develop smart border gates that utilize QR codes, unified databases, and joint diagnostic capabilities to safely fast - track the agricultural supply chain while preventing the spread of diseases like African swine fever.
As noted by a representative of a local company in Manzhouli, a sub - prefectural city in the in the Hulurbuir prefecture - level city jurisdiction within Inner Mongolia Autonomous Region of China, engaged in the import of grains, oilseeds and fodder from Russia, the thorough phytosanitary control carried out by Manzhouli Customs upon receipt of cargoes helps the company to build a comprehensive system of sanitary security and regulatory compliance at all stages, from purchasing and transporting to storing products.
In the long term, this reduces the risks of regulatory breaches and ensures the stability of customs procedures.
It is highlighted that, thanks to the implementation of smart technologies, the efficiency of customs clearance has increased significantly. From the submission of the preliminary declaration to the on - site inspection, approximately two hours elapse, even with large volumes of incoming containers.
According to Chinese authorities, the continuous improvement of intelligent border monitoring systems will contribute to the sustainable development of external economic ties.
