Power plant delays fuel tensions over Rio's giant Mongolia copper mine

Nearly 10 years on from the launch of a giant copper and gold project in Mongolia, Rio Tinto is still looking to secure a domestic power source it needs for the mine under an agreement with the government.

Oyu Tolgoi, located in the South Gobi region near landlocked Mongolia's southern border with China, is scheduled to complete a $5.3-billion underground expansion for first production by 2020, creating one of the world's biggest copper suppliers.
