The U.S. Is Purging Chinese Cancer Researchers From Top Institutions

The NIH and the FBI are targeting ethnic Chinese scientists, including U.S. citizens, searching for a cancer cure. Here’s the first account of what happened to Xifeng Wu.

The dossier on cancer researcher Xifeng Wu was thick with intrigue, if hardly the stuff of a spy thriller. It contained findings that she’d improperly shared confidential information and accepted a half-dozen advisory roles at medical institutions in China. She might have weathered those allegations, but for a larger aspersion that was far more problematic: She was branded an oncological double agent.

In recent decades, cancer research has become increasingly globalized, with scientists around the world pooling data and ideas to jointly study a disease that kills almost 10 million people a year. International collaborations are an intrinsic part of the U.S. National Cancer Institute’s Moonshot program, the government’s $1 billion blitz to double the pace of treatment discoveries by 2022. One of the program’s tag lines: “Cancer knows no borders.”
