The intersection of trade and climate change issues leads to the fragmentation of international trade rules in response to climate change, and the integration of institutional systems between climate change and trade should become the normative orientation of international trade law. The International Climate Convention has been implemented and innovated in the field of International Trade Law, achieving the first convergence of rules on trade and climate change. Since the entry into force of the Paris Agreement, new FTAs such as the CPTPP have achieved the secondary convergence of rules on trade and climate change. However, the formation of the“climate club”by new FTAs has some theoretical and logical loopholes and practical operation difficulties, which is against fairness and justice. From the perspective of regulatory convergence, it is necessary to optimize the global allocation of climate change rules in the international trading system. From the perspective of the community of human climate destiny, China should seize the opportunity of the absence of uniform rules in the field of climate change in trade agreements, respond to the climate change crisis with the Belt and Road Initiatives through FTAs, and actively explore the Chinese-style modernization plan of integrating climate provisions in the field of International Trade Law.
