In January 2011 DEG and FMO approved their loans for the project. Indigenous approval despite conflict about mining (2011) In February 2011, the Panamanian government proposed a new mining law that would facilitate the development of mining projects in indigenous areas, while the indigenous people had asked for a law banning mining in their territories. The proposal and the simultaneous launching of bids for a large copper mining project called Cerro Colorado triggered protests of indigenous people, including local communities from the Barro Blanco area, who blocked the Interamerican Highway for four days. The protests were violently suppressed. The conflict was temporarily ended through the San Felix agreement, signed in the village of San Felix. Construction of the dam began in February 2011. On June 25, 2011, according to the project developer GENISA, the regional congress of the Kädriri, the local group of Ngäbe people, approved by public majority voting that the construction of the dam should continue, after having been authorized to take a decision by the General Congress of the Ngäbe-Buglé. Also in June 2011 the UN Clean Development Mechanism (CDM) Board approved the carbon finance proposal that was to generate part of the revenue stream for the project. On August 25, 2011, a Compensation and Benefits Agreement was signed between GENISA and the Board of the Regional Congress of the Kädriri. International campaign and UN inspection (2012-13) However, the conflict remained unresolved. The government called for a referendum on the dam, but the indigenous leader Silvia Carrera, elected as Cacica General in September 2011, initially rejected it. An international campaign was started to stop construction of the dam and international funding for it. In March 2012 Parliament passed a modified version of the mining law that prohibited mining in the indigenous territory and required the approval of the Ngöbe Buglé General Congress for any future hydroelectric projects. However, the traditional authorities of the Ngöbe criticized Silvia Carrera for having given in. They had asked for a complete ban on hydropower projects to be included in the law. Construction had to be halted in May 2012, because the local population occupied the site. The protests were suspended while "UN inspectors" were expected to visit the area. In September 2012 an inspection team led by UNDP and consisting of representatives of the Catholic Church, the environmental agency ANAM, the electricity regulatory agency ASEP and the project developer GENISA, visited
