Big Chill With China Takes Its Toll On Flow Of Money, People And Ideas

In the next three decades, the United States and China built up the largest trade relationship in the world, along with an acceleration of immigration, investment and academic collaborations between the two.

Now, U.S.-China exchanges through trade, travel and technology are quickly fraying. Higher tariffs are discouraging investment on both sides, while stricter export controls and commercial sanctions are driving Chinese buyers away from American technology products. That decoupling is also affecting the flow of people as well — the hundreds of thousands of American and Chinese students, researchers and entrepreneurs who routinely traverse the ocean between both countries.
