SK Telecom has appointed Park Jung-ho as its new CEO, as the South Korean operator steams ahead into the 5G age.

Park replaces Dong-Hyun Jang as CEO of SK Telecom (Nasdaq: SKM) who took on the position in March 2015. It is something of a lateral move for the two men. Jang is taking Park's old position as CEO of SK Holding C&C.
