German authorities arrest 2 on China espionage allegations – Two Munich residents have been arrested on suspicion of working for a Chinese intelligence service, seeking to obtain and pass on high-tech information with “military applications.”
“In order to obtain access to scientific information about high-tech technologies with military applications, they built up contacts with numerous scientists at German universities and research institutes. Some scientists were lured to China on the premise of delivering lectures to the civilian audiences for remuneration,” prosecutors alleged. “In reality, these presentations then took place in front of associates of state-run weapons companies.”
