The European Economic Security Strategy (EESS) is a major regional economic security strategy framework recently launched by the European Commission. EESS takes the search for supply chain and market resilience as the basic goal, multilateralism and rulesalism as the basic principles, and maintaining market resilience and competitiveness, strengthening international cooperation and improving risk identification tools as the basic content. The legal impact of EESS on China’s economic and trade fields cannot be ignored. The policy basis for achieving a higher level of legal cooperation between China and the EU has been significantly strengthened. China may face a new crisis over rules from the European Union. The external policy environment of China’s economic and trade field may undergo multiple transmutation. China’s countermeasures include a combination of legal and political means to deal with the possible“economic security trap”from the EU; improving China’s economic security protection tools, explore the construction of China’s economic security strategy, optimizing China’sexternal legal and policy environment, and enhancing the resilience of China’s supply chain and external market.In addition, China needs to fully learn from the beneficial practices of the EU, focus on improving the construction of new quality productivity in related industries in China, and expand international cooperation on the premise of ensuring the security of economic development and scientific research.
