First, you need to know the emotional bond between Chinese Malaysians and the Chinese Communist Party, before you can say his actions are not suspicious.
That is just factually incorrect. Most Chinese Malaysians are either Cantonese or Hokkien, with closer ties to Taiwan and Hong Kong than the mainland. A lot of the older folk don't even speak Mandarin. Keep in mind the CCP wasn't even in power when most migrated here.
emotional bond with the CCP is a bit too specific; what I should say is that the older generation Chinese Malaysians always have an emotional bond towards China, especially the PRC.
