Singapore's Ng Ser Miang is set to become the second declared candidate for president of the IOC.
An official with knowledge of the decision tells The Associated Press that Ng will announce his candidacy in Paris on Thursday.
The official spoke on condition of anonymity because the announcement hasn't been made yet.
Ng, an IOC vice president, chaired the organising committee of the inaugural Youth Olympics in Singapore in 2010.
German IOC vice president Thomas Bach announced his candidacy last Thursday.
IOC President Jacques Rogge steps down on September 10 after 12 years at the helm of the International Olympic Committee.
Richard Carrion of Puerto Rico, C K Wu of Taiwan and Sergei Bubka of Ukraine are among other potential contenders for the presidency.
