Newly declassified FBI files have provided fresh insights into the activities of Christine Fang, also known as Fang Fang, a Chinese national suspected of operating as an intelligence asset for China’s Ministry of State Security. Fang arrived in the San Francisco Bay Area around 2011 to study at California State University, East Bay, and subsequently used her positions in campus organizations to build a network of contacts among local politicians, business executives, and municipal leaders.
The investigative records, which gained renewed attention following their August 2026 release, reveal that the FBI monitored Fang after noting her frequent interactions with a suspected Chinese intelligence officer stationed at the Chinese consulate in San Francisco. Federal investigators believed Fang, whose parents were identified in internal bureau files as intelligence officers, sought to influence American political circles. In May 2013, the FBI launched an operation, codenamed "Rusty Thumbs," in an attempt to recruit her as a confidential human source. Undercover agents approached her in Las Vegas, but the recruitment effort was unsuccessful.
Among her most significant political connections was then-council member and future congressman Eric Swalwell. Interview summaries from 2015 and 2016 show that Swalwell admitted to having "physical relations" with Fang on a few occasions between 2012 and 2015. Swalwell, who was unmarried at the time, described these encounters as casual. The investigation also noted that Fang assisted in fundraising for his re-election efforts and facilitated the placement of at least one intern in his Washington office. Fang returned to China in 2015 and was never prosecuted in the United States.
