One of the focuses of this year's virtual Davos is inequality caused by "digital divide". On the sidelines of the virtual Davos 2021, CGTN's Xia Cheng caught up with Zhang Yaqin, former President of Baidu and now Dean of Tsinghua University's AI institute, to discuss the capital and concerns behind digital technologies. Zhang is a panelist at an AI development panel at this year's Davos.
