A Chinese professor at the University of Copenhagen conducted genetic research with the Chinese military without disclosing the connection, the university said, in the latest example of how China's pursuit of military-civilian technology is tapping into Western academia in the strategically sensitive area of biotechnology.

The professor, Guojie Zhang, is also employed by Shenzhen-based genomics giant BGI Group, which funds dozens of researchers at the university and has its European headquarters on the university's campus.

Zhang and a student he was supervising worked with a People's Liberation Army (PLA) laboratory on research exposing monkeys to extreme altitude to study their brains and develop new drugs to prevent brain damage — a priority the PLA has identified for Chinese troops operating on high plateaus.
