Concerns Raised Over Mining Operations Near Myanmar Border

On November 14, 2026, Deputy Interior Minister Jasets Thai-set visited the border area of Ban Phaya Phrai in Mae Fah Luang District, Chiang Rai, to inspect mining operations near the Myanmar border. Accompanied by local security officials and academics, the minister reviewed data regarding 20 mining sites currently authorized by the Myanmar government, including gold mines. Concerns were raised regarding three specific sites—Doi Kor Wan, Muang Kan, and Mae Jok—which are situated in headwater areas that feed into the Mae Sai River. Reports indicate that these mines are actively expanding their infrastructure and machinery, leading to fears that toxic runoff could contaminate local water sources. For residents and visitors in the Chiang Rai region, this situation highlights potential environmental risks to water quality in the area. The government plans to discuss these cross-border environmental concerns with Chinese officials during meetings scheduled for November 16–18. While the potential for increased pollution has been identified by local civil society networks and government officials, the full extent of the environmental impact and the specific regulatory measures that may be taken remain to be confirmed. Authorities continue to monitor the expansion of these mining activities to assess long-term risks to the regional ecosystem.
