History

Historical Context

Following the 1998 Asian financial crisis, Hyundai Motor Company broadened its global footprint by acquiring a majority stake in Kia and later spinning off its semiconductor arm as Hyundai Electronics, which became Hynix in 2001 and was renamed SK Hynix in 2012. These restructurings show how South Korean chaebols have repeatedly turned domestic units into businesses with overseas presence.
