Taiwan's Investigation Bureau has confirmed that a woman followed German scholar Jürgen Kremb, a visiting researcher studying China's intelligence services, during a trip to Alishan in May last year. Kremb, who previously described the encounter to TaiwanPlus, said he believed the woman was a spy. Investigators say the case illustrates China's use of transnational repression against dissidents and critics abroad, though they declined to release further details as the investigation is ongoing.
