Based on the trade data from 2000 to 2019, this paper uses a complex network analysis method to evaluate the dynamics of global pork trade networks and to identify the characteristics of China's pork networks. Moreover, the issue of potential trade partners for China to expand its pork imports in the future has been discussed. The results show that, while the trade links between the countries involved in global pork trade are relatively "scattered" during the past two decades, the core players in the global pork trade networks are relatively fixed. China, as the No.1 pork importing country in the world, has been playing an increasingly important role in the global pork trade networks. As China's pork imports volume grows, North America, Western Europe and South America have been turning into China's main source of imports, and showing a "tripartite" source pattern. To expand its pork imports in the future, China could have a wide range of potential pork trading partners judging from the current global trade networks. On the one hand, China could deepen the trade relations with its traditional pork trade partners, i.e., Germany, Spain, the USA and Brazil. On the other hand, China could seek for new trade partners, for example, expanding pork imports from Italy and Belgium, as well as other neighboring countries such as Thailand and Vietnam.
