FAO’s food production and trade data and Google’s GDELT event data are used to measure the dependence rate of China’s food on importing countries, the strength of geopolitical relations, and the risk index of food dependence on foreign countries, so as to examine the risk of China’s food dependence on foreign countries from the geopolitical perspective. The results show that China's food imports mainly come from five continents of the world, including that soybean imports depend on the Americas, beef imports depend on South America and Oceania, baby food imports depend on Europe, palm oil imports depend on Asia, barley imports depend on Europe and Oceania. Driven by the increase of import dependence rate and the weakening of geographical relationship, China's risk of import dependence on Brazilian soybeans and beef, on New Zealand, France and Germany baby food, on Indonesian palm oil, and on Ukrainian barley is gradually expanding, while the risk of import dependence on Australian and Uruguayan beef and Canadian barley fluctuates sharply. Therefore, while enhancing food self-sufficiency, we should continue to expand food import channels, reduce trade risks, and actively participate in world food and agriculture governance to grasp the initiative of food security.
