The Salween and Mekong rivers, lifelines for millions across Southeast Asia, are increasingly poisoned by upstream mining operations in Myanmar’s Shan and Kachin states. What looks like a local environmental crisis is in fact a regional political economy, where global demand for rare earths and strategic minerals collides with weak governance and contested authority.

Toxic runoff from extraction sites—many linked to Chinese supply chains—has seeped into tributaries such as the Kok, Sai and Ruak. Thai authorities have detected arsenic levels far above safe limits, while the Mekong River Commission has classified contamination in the upper Mekong as “moderately serious.” Yet accountability remains elusive. Mining in conflict zones is often unregulated, fragmented between militias, private firms and informal operators, leaving no clear line of responsibility.

Myanmar’s upstream position makes the problem particularly acute. In Shan and Kachin, where central state control is weak, unregulated mining proliferates. Communities downstream bear the brunt, with polluted water and soil rendering farmland uncultivable.

In Monghpyak Township, Chinese-backed gold mining has displaced farmers, forcing them to sell land that can no longer sustain crops.

The global arsenic market adds another layer. Arsenic, a toxic byproduct of copper, gold and rare earth mining, is produced in large quantities wherever non-ferrous mining expands. China dominates global arsenic production, accounting for nearly 40 percent, meaning contamination often begins before rivers even cross into Myanmar.

Regional governance mechanisms are ill-equipped to respond. The Mekong River Commission lacks enforcement power, relying on state consent. Meanwhile, geopolitical competition between China and the US complicates cooperation. Washington’s push to diversify mineral supply chains risks elevating the strategic value of polluting sites, sidelining environmental accountability.

Thailand, however, is emerging as a potential champion. As a downstream state directly affected by contamination, it has begun advocating independent water monitoring and cross-border scientific collaboration. Crucially, experts argue that ethnic armed organisations in Myanmar must be engaged in environmental governance, since they control much of the territory where mining occurs.

For now, Myanmar’s polluted rivers expose a stark truth: power, profit and pollution are tightly intertwined. Without regional leadership and inclusive governance, accountability will remain out of reach—and the Salween and Mekong will continue to carry the toxic burden downstream.

Both the Chinese overlords and this extremely toxic regime would do absolutely anything in pursuit of cash, and the environment and the quality of life for the average person means less than nothing to them.

Thank you China.
