Naspers Ltd., Africa’s largest company by market value, is boosting investment into its South African online retailer ahead of Amazon.com Inc.’s entry into the country’s fast-growing ecommerce market.

“We are investing a lot more into our businesses,” Phuthi Mahanyele-Dabengwa, chief executive officer of Nasper’s South African unit, said in an interview on Bloomberg TV Wednesday. “We are well positioned toward being able to deal with whatever could be coming from Amazon.”
