Samsung chairman Lee Kun-hee was released from hospital on Friday. Lee was in the Samsung Medical Center in Seoul for 10 days due to cold and fever, which developed into suspected pneumonia.
Medical staff were concerned when Lee's condition did not improve, but last Wednesday he apparently started to recover.
Rumors that the tycoon was in critical condition were spreading quickly.
Lee will rest at his home in Hannam-dong, Seoul before leaving for the International Olympic Committee session in Buenos Aires on Sept. 7.
