I had exactly the same experience. I think it reflects a few problems here.
One is that our enforcement departments, including the police and the RCMP, do not have the necessary expertise and knowledge about foreign interference. Therefore, we need to make sure they are being educated. There probably should at least be some kind of exchange or training workshop to bring up their level of understanding, so they know exactly what to do when they are being asked to investigate these police stations.
Two is that the language skills are very limited. The majority of them do not speak Mandarin, Cantonese nor Fujanese. That's why I asked for the enhancement of the capacity.
