CHIANG MAI– A large group of Thai environmental activists recently gathered outside the Myanmar Consulate in Chiang Mai . They demanded an immediate end to toxic mining operations located just across the border today. These controversial Chinese-run mines are severely polluting the vital Kok River and surrounding border waterways.
The organized protest happened just days before Myanmar’s military leader, Min Aung Hlaing, visits Thailand. Residents and academic experts joined forces to deliver a strong message to both governments. They want urgent action to stop dangerous heavy metals from freely flowing into their communities.
Key Takeaways
- Activists in Chiang Mai are peacefully protesting against toxic mining in Myanmar that pollutes Thai rivers.
- Over 120,000 people in Chiang Rai currently rely on local tap water heavily contaminated with heavy metals.
- Protesters firmly demand that Myanmar’s military government immediately halt all border mining operations to protect communities.
Activists Demand Immediate Action from Myanmar Leadership
The Kok River Protection Network organized this peaceful demonstration in front of the local consulate building. Nearly 50 police officers were deployed to closely monitor the activists and fully secure the area. Despite the heavy security presence, the crowd remained completely peaceful while verbally expressing their deep frustrations.
Protesters used creative symbolic actions to highlight the ongoing environmental disaster affecting their local water supplies. Some wore unique masks depicting Thai Prime Minister Anutin Charnvirakul and Myanmar military leader Min Aung Hlaing. They tossed bottles of dirty water back and forth to effectively represent the shared border pollution.
Dr. Suebsakul Kitnukorn, a highly respected academic from Mae Fah Luang University, helped lead the local demonstration. The organized group eventually submitted a formal letter of complaint through local police superintendent Sawek Choosiri. This very important document was officially forwarded directly to the Myanmar consulate for their immediate review.
Severe Health Risks Threaten Millions of Thai Citizens
Millions of Thai citizens living along the Kok, Sai, Ruak, and Mekong rivers face severe health risks. The local food chain is becoming heavily contaminated with dangerous chemicals flowing from the mining sites. Farmers are now unfortunately forced to use this highly toxic water for their daily agricultural needs.
At least 110,000 rai of agricultural rice fields currently rely on this heavily polluted water source. These struggling farmers are unknowingly selling contaminated crops to unaware consumers across the entire Thai country. The widespread impact of this toxic water pollution on the national food supply is growing increasingly alarming.
Local fishing communities are also suffering greatly from this transboundary environmental crisis daily. Fishermen in 60 different border villages can no longer safely practice their traditional daily river livelihoods. Consumers are actively refusing to buy fresh fish that might contain dangerous lead, cadmium, or mercury.

Myanmar Junta Denies Ongoing Environmental Damage Claims
The Thai Ministry of Public Health has officially advised against eating certain local river seafood products. Concerned citizens are clearly warned to avoid consuming shrimp, shellfish, crabs, and fish innards from these rivers. Furthermore, at least 120,000 everyday residents in Chiang Rai city are drinking contaminated tap water daily.
The United Nations previously addressed this massive environmental crisis in a formal joint international communication letter. On April 21, 2026, they clearly highlighted the ongoing human rights and environmental violations in the region. The UN strongly urged the responsible national governments to take immediate action against the massive mining pollution.
However, the military government in Myanmar completely rejected these serious international allegations shortly after receiving them. On June 17, 2026, they sent a formal reply strongly denying any rare earth mining activities happening. They falsely claimed that no such destructive operations currently exist along the banks of the Kok River.

The Urgent Need for Cross-Border Environmental Cooperation
Environmental groups strongly argue that this official denial directly contradicts clear evidence from modern satellite imagery. Local activists rightfully view the junta’s response as a blatant insult to both the UN and Thai citizens. The clear visual evidence shows massive environmental destruction happening right along the affected riverbanks even today.
The Kok River Protection Network continues to demand full accountability from the Myanmar military government. They insist that political leaders must publicly acknowledge the devastating pollution flowing directly into neighboring countries. Stopping these toxic mining operations is currently the only way to ensure long-term regional safety.
Dedicated activists state that all mining activities along these important transboundary rivers must be suspended immediately. These destructive operations should really only resume once the severe water contamination issues are completely resolved. The overall health and safety of millions of regional people must be prioritized over corporate mining profits.
