SK chief thinks North Korea can be test bed for 'future cities'

SEOUL -- North Korea is well-positioned to test new economic models and technologies for the cities of the future because there is little infrastructure and antiquated industrialization standing in the way, according to the head of South Korea's third-largest conglomerate.

SK Holdings Chairman and CEO Chey Tae-won was among the group of business leaders who visited North Korea in September with Samsung Electronics Vice Chairman Lee Jae-yong, Hyundai Motor Vice Chairman Kim Yong-hwan and LG Group Chairman Koo Kwang-mo.
