Rio Tinto PLCProtesters block copper exports from Oyu Tolgoi, threatening supply and contractual duties.

Protesters blocked copper exports from Rio Tinto's Oyu Tolgoi mine in Mongolia on Wednesday, threatening the supply of copper concentrate to China. The group, demanding a greater share of mining revenue for Mongolians, began a blockade of a key road from the mine, preventing trucks from hauling copper concentrate to the border. Rio Tinto warned of a risk of not fulfilling contractual duties and said the disruption could inflict significant disruptions to the state budget and tarnish Mongolia's reputation. Oyu Tolgoi is one of the world's most significant copper projects and is still ramping up to full capacity that would see it become the world's fourth-largest operating copper mine. Rio Tinto operates the mine with a 66% stake, while the Mongolian government owns the rest.
