A briefing...outlines findings from research carried out in DRC's North and South Kivu provinces, Burundi and Rwanda in March and April 2013...Tonnes of gold produced in eastern Congo benefit rebels and high-ranking members of the Congolese and Burundian state armies. The gold is laundered through Burundi’s domestic gold sector and exported to Dubai. Neither local buyers in the Great Lakes region nor international traders conduct adequate checks on the gold they purchase to ensure that it has not funded conflict or human rights abuses in eastern Congo...Much of the tin, tantalum and tungsten produced in North and South Kivu benefits rebels and members of the state army. The minerals are smuggled out of Congo into Rwanda and Burundi for export. Tin and tantalum smuggled into Rwanda is laundered through the country’s domestic tagging system and exported as ‘clean’ Rwandan material.
