Constancia, a copper mine in Cuzco owned by the Canadian company Hudbay, is embroiled in conflict with the surrounding communities in the province of Chumbivilcas. These claim that the trucks that transport copper to port cause serious environmental and health damage in ways similar to the problems arising at Las Bambas. The communities demand that Hudbay tarmac the road. The company has asserted that it is acting in good faith and has been taking part in dialogue. It claims to have signed an agreement with Provias Nacionales, an agency of the ministry of transport and communications, to maintain the road, although it has no legal obligation to do so. They say that their representatives were denied access to the round table dialogue meeting which was then suspended and a 72-hour strike declared.
On 22 February, the government declared a 30-day state of emergency
The state of emergency puts all public order issues into the hands of the police with supportive action from the armed forces.
