Lee Kun-hee, chairman of Samsung Group, the country's biggest conglomerate, returned home Thursday to presumably oversee the group's reorganization after spending more than three months overseas. "As you can see, I am alright," Lee, 72, responded to reporters asking about his health. He did not answer any other questions. Lee had briefly returned to Seoul late last year to participate in the group's New Year's ceremony. He left about two weeks later and reportedly stayed mostly in Japan. He had spent seven months abroad in 2013, including a trip to the International Olympic Committee (IOC) meeting.
