To fully utilize both domestic and overseas markets and resources, which was put forward by the Party Central Committee and the State Council, it's of great significance to accurately analyze the trade situation of agricultural products in China and scientifically grasp the reasonable scale of the import of agricultural products. This paper analyzes the general situation changes and driving factors of China’s agricultural products trade after China’s entry into WTO, and probes into the current situation of China’s major agricultural products trade in terms of varieties and markets. Furthermore, we estimates the reasonable import scale of major agricultural products in 2025 and 2030, such as wheat, rice, corn, cotton, sugar, soybean, vegetable oil, pork, beef, mutton, poultry meat, and aquatic products. Policy proposals of ensuring the basic supply of grain and bulk agricultural products at home, adopting active import strategy, improving the international agricultural product market monitoring and import early-warning mechanism, and promoting the “going global” strategy of agriculture are put forward.
