But Wang stopped short of saying whether Tang was being deliberately sheltered by diplomats.
"We urge the US to stop using any excuse to limit, harass and crackdown on Chinese scholars and Chinese students in the US," he said.
In addition to Tang, 3 other Chinese nationals have also reportedly been charged.
As the US and China engage in unprecedented tit-for-tat closures of diplomatic missions, destabilizing financial markets and sending a chill through the international community, a DOJ official has confirmed that a Chinese researcher who was reportedly "hiding out" at the Chinese consulate in San Francisco has been taken into custody.
The Chinese researcher, Juan Tang, had been affiliated with the University of California at Davis, and was to be charged with lying about her military service, when she sought shelter at the Chinese consulate in San Francisco.
