The FBI is walking a tightrope on China

• Lieber is a rare case of a non-Chinese person arrested for failing to disclose China ties.

Background: Working with the National Institutes of Health, the FBI launched a sweeping investigation into research institutions' links to China last year.

A recent report proposes existing disclosure practices should be enough to address foreign influence in research, including problems with coercion and theft.

• But the process of disclosure isn't standardized across agencies and institutions and can be unclear for researchers.
• "Improving disclosure and transparency is probably the most important recommendation," Remco Zwetsloot of Georgetown's Center for Security and Emerging Technology said of the report from the JASON program at MITRE Corp. "Universities and scientists are asking for clarification in guidance and standardization across the agencies."

The spate of investigations, largely of ethnic Chinese scientists and researchers, has raised fears that another era of race-based targeting may be nigh.

• Former China correspondent Mara Hvistendahl reveals in her new book "The Scientist and the Spy," out yesterday, that in the height of the Cold War the FBI spent years spying on Chinese scientists and students in the United States. Some lost their careers permanently without ever facing formal charges.

The bottom line: Law enforcement officials have to tread carefully to protect U.S. research and civil rights.
