摘要:The International Maritime Organization (IMO) plays a significant role in global marine environmental governance, providing a forum of regulatory oversight for member states. Member states are the main actors of the IMO and exert considerable influence on the process of lawmaking. Among these member states, China is unique due to its multiple identities. There are various factors influencing interests behind China’s multiple identities, which fully engage the country in various shipping and maritime trade activities. This article examines China’s role in the IMO marine environmental regulatory governance. It identifies the impact of China on global ocean governance and indicates the development and reforms in the global governance system. China enacted the China Ocean Agenda 21 for its strategy of ocean development. Thus, China is the object of study in this examination of empirical research that collects submissions from 2001 to 2020 related to marine environmental governance. The findings reveal that the extent to which China participates in such governance has considerably increased, and although the contribution of China’s submissions is still in development, its role in the IMO is no longer merely that of a follower, and the efforts of the country have had a positive influence on the IMO’s marine environmental regulatory governance, including its legal instruments.
