Conflict resource
Conflict resources are natural resources extracted in a conflict zone and sold to perpetuate the fighting. There is both anecdotal and statistical evidence that belligerent accessibility to precious commodities can prolong conflicts (a ""resource curse""). The most prominent contemporary example is the eastern provinces of the Democratic Republic of the Congo, where various armies, rebel groups, and outside actors have profited while contributing to violence and exploitation during wars in the region.The most commonly mined conflict minerals are cassiterite (for tin), wolframite (for tungsten), coltan (for tantalum), and gold ore, which are extracted from the Eastern Congo, and passed through a variety of intermediaries before being purchased by multinational electronics companies. These minerals are essential in the manufacture of a variety of devices, including consumer electronics such as mobile phones, laptops, and MP3 players.The extraction and sale of blood diamonds, also known as ""conflict diamonds"", is a better-known phenomenon which occurs under virtually identical conditions.Various international efforts have been made to reduce trade in conflict resources, to reduce the incentive to extract and fight over them. For example, in the United States, the 2010 Dodd–Frank Wall Street Reform and Consumer Protection Act requires manufacturers to audit their supply chains and report conflict minerals usage.
