The Oyu Tolgoi project has been mired in controversies for a long time. Resource nationalists in Mongolia have been pressing for renegotiation of the contract which the Mongolian government signed with Rio Tinto. Yielding to their demands, the Mongolian government has thus far twice requested Rio Tinto to renegotiate terms of their agreement. Rio has chosen to reject the demand both times. Local communities in the South Gobi province, where the mine is located, have their own grievances which they have been vociferous about. The power supply hurdles had only made things tougher for Rio which is keen to start production on time. [2]
