Samsung Electronics co-CEO Han Jong-hee dies of cardiac arrest

South Korean tech giant Samsung Electronics said on Tuesday that its co-chief executive officer Han Jong-hee has died due to cardiac arrest. Han was in charge of Samsung's consumer electronics and mobile devices division, while co-CEO Jun Young-hyun oversees the chip business of South Korea's biggest company. Han died at a hospital on Tuesday while being treated for cardiac arrest, a company spokesperson said, adding that a successor had not yet been decided. Samsung Electronics shares were flat in morning trade. The South Korean firm has been suffering from weak earnings and sagging share prices in recent quarters after falling behind rivals in advanced memory chips and contract chip manufacturing, which have enjoyed strong demand from artificial intelligence projects.
