Rio Tinto and the Mongolian government are in ongoing negotiations over funding and control of the massive Oyu Tolgoi copper and gold mine project. While talks continued in March, disagreements remain over taxes, cost overruns, and management control. Failure to resolve the dispute could have serious negative consequences for Mongolia's economy and businesses that supply the mine project. Deputy Minister of Economic Development warned of a "catastrophe" if the project stops, as Oyu Tolgoi is expected to account for 30% of Mongolia's economy at full production. Mongolia's businesses are already feeling the effects of the uncertainty through slower contract awards and a general slowdown related to the mine project.
