Protesters block Rio Tinto copper exports at Oyu Tolgoi

Protesters on June 17 blocked copper concentrate exports from Rio Tinto's Oyu Tolgoi mine in Mongolia's Gobi Desert. The Anglo-Australian miner confirmed in a Facebook statement that shipments have been disrupted. The blockade threatens to halt the flow of copper from one of the world's largest known copper and gold deposits. No group has claimed responsibility, and the specific demands of the protesters remain unclear.
