In theory American and European buyers of gold in Africa are required to review their supply chain and report any use of conflict resources, such as gold from eastern Congo. In practice the requirement is widely ignored, and an investigation by African Network of Centers for Investigative Reporting (ANCIR) found examples in the leaked Mossack Fonseca documents of anonymous shell companies doing the sourcing. For a start, most of the DRC gold winds up in Dubai by way of Uganda. Dubai's $75 billion gold industry is regulated with a very light hand by the quasi-private Dubai Multi Commodities Centre (DMCC).
Initial reports identified five then-heads of state or government leaders from Argentina, Iceland, Saudi Arabia, Ukraine, and the United Arab Emirates as well as government officials, close relatives, and close associates of various heads of government of more than forty other countries. Names of then-current national leaders in the documents include President Khalifa bin Zayed Al Nahyan of the United Arab Emirates, Petro Poroshenko of Ukraine, King Salman of Saudi Arabia, and the Prime Minister of Iceland, Sigmundur Davíð Gunnlaugsson.
The Panama Papers are an unprecedented leak of 11.5m files from the database of the world’s fourth biggest offshore law firm, Mossack Fonseca. The records were obtained from an anonymous source by the German newspaper Süddeutsche Zeitung, which shared them with the International Consortium of Investigative Journalists (ICIJ). The ICIJ then shared them with a large network of international partners, including the Guardian and the BBC.
