The US government is open to easing sanctions on billionaire mining magnate Dan Gertler if he gives up his business operations and assets in the Democratic Republic of Congo, where Washington’s interest in critical minerals has run up against his problematic royalties ownership. The Treasury Department is willing to grant limited sanctions relief to Gertler, an Israeli citizen, as a way to incentivize his complete exit from Congo, including relinquishing his royalty streams on three strategic projects, according to two US officials, who asked not to be identified as the talks are ongoing.
