Quick Take The Mongolian government and Rio Tinto are locked in a dispute over high management fees, cost overruns and transparency in the Oyu Tolgoi project. The Mongolian government representatives on Oyu Tolgoi's board had refused to approve the mine's budget in January this year, demanding an explanation for a cost inflation by $2 billion. The situation has been complicated by the upcoming presidential elections in June because no politician wants to be seen selling out to Rio Tinto, especially when they all have promised to garner a greater share of profits for the country.
