Thailand and Myanmar Address Cross-Border River Pollution Crisis
Thai officials are engaging in high-level diplomatic talks with Myanmar to address toxic heavy metal contamination in the Kok, Sai, and Mekong rivers originating from Shan State mining operations.
A persistent environmental crisis involving toxic contamination in the Kok, Sai, and Mekong rivers has prompted urgent diplomatic efforts between Thailand and Myanmar. According to Khaosod Online, the pollution, which includes arsenic, lead, and cadmium, has affected seven provinces, including Chiang Rai, Chiang Mai, Mae Hong Son, and Loei, since late 2024. The contamination is linked to gold and rare earth mining in Myanmar's Shan State, where operations lack adequate waste treatment. Thai Deputy Prime Minister Sihasak Phuangketkeow recently met with Myanmar's leadership to establish a joint working group, scheduled to convene on November 25-26. Prime Minister Anutin Charnvirakul is also seeking cooperation from China to address the situation in the Shan State mining areas. While the government is prioritizing diplomatic negotiations, civil society groups and academics are calling for a temporary ban on the import of high-risk minerals and greater transparency regarding the companies involved. For residents and travelers, the situation highlights ongoing concerns regarding water quality in affected northern regions. It remains to be confirmed whether the Thai government will implement stricter import controls or if the diplomatic talks will lead to effective remediation of the mining sites in Myanmar.
