Northern Thai community networks handed a statement to Myanmar's junta chief in Chiang Mai, demanding action on heavy-metal pollution from Myanmar mining in the Kok, Sai, Ruak and Mekong basins. They ask Thailand to stop signing the draft Thailand-Myanmar TOR, which they say cuts joint water-quality monitoring and international oversight, and to halt all mineral imports from Myanmar. Customs data cited shows imports of antimony, copper, lead, tin, tungsten and manganese through several border crossings, shipped via Laem Chabang. The Chiang Rai waterworks is seeking over 2,000 million baht to find a new raw-water source. Businesses in border trade, mineral import/logistics, and food from the Kok and Mekong should watch for possible import restrictions and water-quality advisories; no decision has been made yet.
