Not everyone in the chain is breaking the law. Miners, some of them working legally, typically sell the gold to middlemen. The middlemen either fly the gold out directly or trade it across Africa’s porous borders, obscuring its origins before couriers carry it out of the continent, often in hand luggage. For example, Democratic Republic of Congo (DRC) is a major gold producer but one whose official exports amount to a fraction of its estimated production: Most is smuggled into neighbouring Uganda and Rwanda. “It is of course worrisome for us but we have very little leverage to stop it,” said Thierry Boliki, director of the CEEC, the Congolese government body that is meant to register, value and tax high-value minerals like gold.
The customs data provided by governments to Comtrade, a United Nations database, shows the UAE has been a prime destination for gold from many African states for some years. In 2015, China – the world’s biggest gold consumer – imported more gold from Africa than the UAE. But during 2016, the latest year for which data is available, the UAE imported almost double the value taken by China. With African gold imports worth $8.5 billion that year, China came a distant second. Switzerland, the world’s gold refining hub, came third with $7.5 billion worth.
Most of the gold is traded in Dubai, home to the UAE's gold industry.
The UAE reported gold imports from 46 African countries for 2016. Of those countries, 25 did not provide Comtrade with data on their gold exports to the UAE. But the UAE said it had imported a total of $7.4 billion worth of gold from them.
In addition, the UAE imported much more gold from most of the other 21 countries than those countries said...
