A Harvard University department chair and two Chinese nationals who were researchers at Boston University and a Boston hospital were charged on Tuesday with lying about their alleged links to the Chinese government.
The charges are part of an aggressive effort by U.S. authorities to block what they say are Chinese attempts to steal American scientific and technological advances.
"This is a very carefully directed effort by the Chinese government to fill what it views as its own strategic gaps," Andrew Lelling, U.S. attorney for the District of Massachusetts, told a news conference.
