Tensions between the world's superpowers are mounting in Washington, D.C., and Beijing. But between these hubs of high-level politics, an entirely new reality is emerging. Yet the People's Republic of China and the state of California have built deep and interdependent socioeconomic exchanges that reverberate across the globe, and these interactions make California a microcosm of the most important international relationship of the 21st century.

In The Transpacific Experiment, journalist Matt Sheehan chronicles the real people who are making these connections. Sheehan tells the story of a Southern Californian mayor who believes a Chinese electric bus factory will save his town from meth labs and skinheads. He follows a celebrated Chinese AI researcher who leaves Google to challenge his former employer from behind the Great Firewall. Sheehan joins a tour bus of wealthy Chinese families shopping for homes in the Bay Area, revealing disgruntled neighbors and raising important questions about California's own prejudices.

Sheehan's on-the-ground reporting reveals movie sets in the "Hollywood of China," Chinese immigrants who support Donald Trump, and more. Each of these stories lays bare the new reality of 21st-century superpowers: The closer they get to one another, the more personal their frictions become.
