In July 2020, a report released by an NGO, Swissaid, denounced the gold trade between Dubai and Switzerland. The documents revealed that Dubai firms, including Kaloti Jewellery International Group and Trust One Financial Services (T1FS), have been obtaining gold from poor African countries like Sudan. Between 2012 and 2018, 95 per cent of gold from Sudan ended up in the UAE. The gold imported from Sudan by Kaloti was from the mines controlled by militias responsible for war crimes and human rights violations in the country. World's largest refinery in Switzerland, Valcambi, was denounced by Swissaid for importing extensive gold from these Dubai firms. In 2018 and 2019, Valcambi received 83 tonnes of gold from the two companies.
