There came a point ten years ago when Aynne Kokas realized that she could no longer keep WeChat on her personal phone. She had begun research on what would eventually become her new book, “Trafficking Data: How China is Winning the Battle for Digital Sovereignty,” published this month. 

WeChat is an omnipresent Chinese messaging app, and Kokas, a media studies professor at the University of Virginia, needed it to talk to Chinese sources for her research. But, as Kokas told me, it soon became “a very meta experience.” To have WeChat on her personal phone meant that “you were subjecting yourself to precisely the type of surveillance that you were writing about.”

In the book, Kokas analyzes how Chinese firms and the Chinese government gather data on U.S. citizens for political and commercial gain, putting U.S. national security at risk. China is able to do this, Kokas points out, in part because the U.S. government does not have substantial regulations in place to protect users and their data.

“By tracing how China and the US have shaped the global movement of data, I hope this book empowers citizens around the world to navigate the complex terrain created by Silicon Valley, Washington, and Beijing,” she writes.
