The bloc also said the number of Japanese eels has been sharply declining, claiming that all eel species should be listed as endangered under Appendix II to the Washington Convention, also known as the Convention on International Trade in Endangered Species of Wild Fauna and Flora. A listing on Appendix II means that the species may become extinct if trade is not closely regulated. Japan's government has insisted the country has sufficient resources of Japanese eels, which are not at risk of extinction, due to international trade.
