For thirty years Inco enjoyed a cozy relationship with the repressive and corrupt Suharto regime.
Members of the Karonsi’e Dongi and Sorowako indigenous communities lost their most productive agricultural land when the PT Inco mine was built, and they received paltry compensation in return. Mining activity has degraded land and water resources, and initial monitoring suggests that smelter emissions affect air quality in neighbouring communities. Despite apparent efforts by Inco to resolve community claims in recent years, protesting residents report being threatened and intimidated by the Indonesian military and police.
