Chinese espionage in the European Union and neighboring countries reveals its full scope when certain pieces are connected. The May 20 arrest in Germany of a German couple of Chinese origin who were taking military-technology information from universities is a particularly notable case. But it is only one of many. The episode exposes a strategy of large-scale, coordinated infiltration when placed alongside other arrests in EU member states and neighboring countries. In total, around 30 agents and collaborators have been uncovered in Europe and its vicinity in just the past two years; some were arrested, several expelled, and others are awaiting trial. China typically denies all espionage allegations and describes them as slander.
