Factors such as the escalating Ukraine crisis，climate change and the adoption of the BBNJ Agreement are changing the international seascape of Arctic fishery governance. On the one hand，Arctic fishery has become a valuable platform for international cooperation under the increasingly serious regional conflict and related security situations；on the other hand，changes in the distribution of fishery resources and new developments in international legislation have，to some extent，undermined the stability of current Arctic fishery governance and promoted new changes in the laws and policies of Arctic coastal states. Arctic fishery provides an important platform for China to participate in Arctic affairs. From the perspectives of international politics and law，China should continue to remain well-informed of the situation in the Arctic region，the relevant international legal framework and new developments in the policies and practices of Arctic coastal states. China should conduct dialogue in Arctic fishery with other countries，and expand cooperation to shipping，scientific research，environmental protection and other fields. We should be alert to the potential risks posed by the United States and others with regard to how they deal with Arctic issues and those relating to the South China Sea as a whole in terms of denying China’s maritime rights and interests. We should respond with the tool of international law and assume a lead role in the development of relevant international law principles and rules.
