Ivan Kagame's appointment to the Rwanda Development Board was announced by the prime minister’s office on Monday.
The board was responsible for the signing of multi-million dollar sponsorship deals with top European football clubs Arsenal and Paris Saint-Germain to promote tourism in the East African nation.
Thirty-year-old Ivan Kagame is rarely seen in media or social media and has so far avoided dabbling in politics. He holds a business degree from an American university.
Meanwhile, Rwanda's cabinet has extended coronavirus containment measures after it partially lifted a nationwide lockdown about three weeks ago. Bars, schools and places of worship will remain closed. A night-time curfew will now start an hour later at 21:00 local time.
President Kagame also pardoned 50 "young women" convicted for abortion and 3,596 prisoners will be conditionally released.
