Guidelines for Resolving the Cross-Border Haze Problem in Chiang Rai Province through a Chiang Rai-Yunnan “Sister City” Cooperation Framework

Abstract

The haze issue in Chiang Rai Province has persisted for several years, exacerbated by both local and transboundary air pollution. Efforts under the ASEAN Agreement on Transboundary Haze Pollution (AATHP) have proven insufficient in adequately addressing the problem. China, particularly Yunnan Province, has been recognized for its effective policies and measures to mitigate transboundary haze. This article aims to investigate China’s policies and strategies—specifically in Yunnan Province—for mitigating haze problems and to provide insights for resolving the transboundary haze issue in Chiang Rai Province. The study emphasizes the use of collaborative frameworks, facilitated through Sister City cooperation, to address haze issues by leveraging existing relationships and favorable geopolitical conditions. The research is conducted using documentary research methods, involving the collection and analysis of relevant documents to draw conclusions. The results indicate that the problem can be addressed through three approaches: 1) promoting knowledge exchange among public sectors and citizens, 2) strengthening Thai-Chinese cooperation to negotiate with Laos and Myanmar, and 3) establishing collaborative frameworks on specific issues, including the consideration of legally binding implementations.
