Environmental Fallout: Myanmar's Rare Earth Exploitation and Thai Rivers

Standing by the Sai River, overlooking its waters, Bundit Pantarakon, a local figure involved in business and governance in Mae Sai, Thailand, observes the region's predicament.

In the picturesque locale of Tha Ton, Thailand, the Wat Tha Ton Temple offers sweeping views of the winding Kok River valley extending south, meandering through the mountainous terrain from Myanmar to the north. Residents, including local educator Prasert Guytuan, recount noticing changes in the river's condition nearly two years ago. The watershed’s clarity diminished noticeably and irritating qualities emerged simultaneously with the initiation of a mining operation just across the border.

Previously a vital source for various community activities such as bathing and cleaning, the river now induces skin irritations, notes Guytuan, prompting villagers to shun its water. Alarmed by these developments, the Department of Pollution Control commenced investigations.

Recent analyses revealed that pollutants, far exceeding WHO guidelines, now permeate a river system stretching 150 miles through Thailand's Chiang Rai province, ultimately merging with the massive Mekong River. Elevated arsenic concentrations were detected this month. Pianporn Deetes, advocating for International Rivers, expresses grave concern over these findings.

Activists attribute the deteriorating water quality to Myanmar's unregulated mining ventures in Shan State, particularly those extracting rare earths and gold. These minerals are crucial for modern manufacturing, from electronics to military needs. China dominates their production, and Myanmar has become an increasingly significant unregulated supplier.

The once-pristine Kok River has fallen victim to this unchecked mining rush.

In Mae Sai, local leader Bundit highlights how nearby mining sites — visible even from satellite imagery — have contaminated waterways, stirring unrest among communities reliant on these water sources.

Evidence of pollution is visible in ailments affecting residents, including Bundit, who attributes his recent rash to waterborne toxins. After severe flooding, tests revealed high arsenic levels in well water along the river. Authorities advise against utilizing river water ahead of further deterioration.

International Rivers' Pianporn Deetes warns of impending threats to populations along the river systems should this issue remain unaddressed, exacerbated in part by Myanmar's ongoing internal conflicts.

Experts like Brian Eyler from the Stimson Center liken the current situation to a lawless wasteland, where mining proceeds unabated by regulations or authority interventions.

The mining zones fall under the sway of the United Wa State Army (UWSA), a robust ethnic militia with complex ties to various illicit trades. Operating with a degree of autonomy, the UWSA governs and controls these territories — with strong ties to China.

The export of rare earths from Myanmar to China is well-documented and growing, as conveyed by David Merriman of Project Blue. While China's environmental policies have become stricter domestically, prompting businesses to relocate operations, Myanmar's regulatory laxity presents fewer obstacles.

Merriman describes China's hands-off approach, suggesting they view these matters as Myanmar's responsibility. The arrangement benefits China, sustaining its supply chain without assuming direct accountability for environmental repercussions.

Local activist Niwat Roykaew, based along the Mekong, seeks China's intervention to mitigate environmental and health hazards stemming from these mining practices. His endeavors have previously convinced Thai authorities to reject projects potentially empowering Chinese navigation on the Mekong, while also confronting ecological damage from Chinese dam constructions.

The immediacy of toxin proliferation threatens not only human health but also local wildlife and agricultural viability, destabilizing entire ecosystems reliant on the Mekong's resources.

Roykaew calls for China's diplomatic engagement to temper the unruly mining pursuits of the UWSA, emphasizing mutual benefits. Recent dialogues between Thai and Chinese representatives, as well as official acknowledgments of heavy metal contamination, offer a tentative pathway toward change.
