China might be using a suspected leak of personal information from the Eslite bookstore chain to wage cognitive warfare against Taiwanese, the Taiwan Statebuilding Party said yesterday.

Cynthia Yang (楊欣慈), deputy secretary-general of the Here I Stand Project, told a news conference in Taipei that she received a telephone call on Saturday night from a woman who said she worked at Eslite’s marketing department.

The woman asked Yang if she wanted to participate in an opinion survey the company is conducting among its customers.
