The family office for Nicky Oppenheimer and his son Jonathan has set up an outpost in Singapore to boost its Asia exposure and partner with the region's wealthy, Bloomberg said.
The move comes as local media reported the city-state was stepping up its bid to be the premier family office hub in the region.
The Oppenheimer family founded Anglo American and sold its 40% stake in De Beers to Anglo in 2012.
The family now has a combined net worth of $8.2 billion, according to the Bloomberg Billionaires Index.
"We look forward to deepening relationships with like-minded partners," the family office's executive chairman Jonathan Oppenheimer said, the wire service reported.
