Protests blocked a key road on Wednesday, halting copper concentrate shipments from Rio Tinto's Oyu Tolgoi mine in Mongolia. Demonstrators are demanding a larger portion of the mine's revenue for the Mongolian people.

Rio Tinto’s local subsidiary warned the disruption creates a risk of failing to fulfill contractual duties. This impasse could impact the Mongolian state budget and damage the nation's reputation in the international mining sector.

Rio Tinto shares fell approximately 1.6% in London trading following the news. Oyu Tolgoi is projected to become the world’s fourth-largest copper mine at full capacity and remains central to the company’s energy transition growth strategy.
