The Eurasian Economic Union (EAEU) was established in 2015. At present, Russia, Kazakhstan, Belarus, Kyrgyzstan and Armenia are member countries. They are all important partners in the construction of the “Belt and Road” initiative. The mandatory technical regulations on animal aquatic products and their products from the EAEU were collected and summarized. The similarities and differences of key contents in relevant EAEU regulations and China's national food safety standards such as definitions, scopes and categorizations of animal aquatic products and their products, as well as maximum levels of contaminates and pathogenic bacteria, parasitological safety requirements and veterinary drug residues were compared and analyzed. The possible causes of the above similarities and differences of animal aquatic products and their products were briefly discussed. The article could provide references for promoting trade in animal aquatic products and their products between China and EAEU member states, avoiding or resolving potential trade barriers and other issues, as well as for further exchanges and cooperation in technical regulations and standards between the two parties.
