In a pre-market statement, Amsterdam-based Prosus said an article in Asian Tech Press citing unnamed sources saying that Naspers was in talks with a group of investors led by CITIC of China to sell its entire Tencent stake was "speculative and untrue".

Prosus holds a 28% stake in Tencent worth $70 billion at current prices. It has said it intends to sell the stake down gradually to fund a share repurchase program.

"The Naspers Board and Prosus Board reiterate their continued confidence in Tencent's long term prospects and continue to believe that the share repurchase programme is in the best interests of Prosus, Naspers and their respective shareholders," they said in a statement.
