The news organization reported that it had sought information on her whereabouts from the Chinese government and the Chinese embassy in Washington, D.C., this week.
On Thursday, the company “received confirmation that Fan is being held on suspicion of participating in activities endangering national security.”
“We are very concerned for her, and have been actively speaking to Chinese authorities to better understand the situation,” the company said in a statement to CNN Business on Friday. “We are continuing to do everything we can to support her while we seek more information.”
China’s Ministry of Foreign Affairs said in a statement on Friday that Fan was detained “on suspicion of engaging in criminal activities that jeopardize national security,” adding that the case is under investigation and her “legitimate rights have been fully ensured.”
The Foreign Correspondents’ Club of China said it was “very concerned” to learn about Fan’s detention.
“Chinese nationals offer critical research and linguistic support for foreign reporting in China. Without their support, it would be difficult for foreign media to operate in China,” the club said in a statement.
Chinese nationals are only permitted to work for foreign news outlets in “auxiliary” roles and must be hired through a Foreign Ministry-affiliated agency.
