Dust pollution has recently become a shared environmental issue for both China and South Korea. This paper reviews the progress of China-South Korea cooperation on dust pollution control since the establishment of diplomatic relations in 1992, covering developments and achievements in policy dialogue, technical exchanges, and joint research. Additionally, this paper highlights the issues and challenges in China-South Korea environmental cooperation, such as the impact of political and economic factors, insufficient cooperation mechanisms, and low levels of public engagement. Finally, with a view to the future, this paper proposes three policy recommendations to advance environmental cooperation between the two countries: 1) strengthening bilateral cooperation to enhance the sustainability of environmental policies; 2) improving multilateral cooperation mechanisms to promote technological innovation; and 3) encouraging public participation to build a diversified governance framework. Finally, it is recommended to further refine the public participation pathways in future cooperation, incorporating successful case studies, and to clarify the division of responsibilities among the stakeholders in the multilateral cooperation mechanism to enhance the feasibility of the collaboration.
