British website The Conservative Woman reviews a new book by Canberra academic Clive Hamilton: "Silent Invasion: China's influence in Australia."
Apparently, last year Chinese parties nearly defenestrated an Australian MP in a key Sidney constituency, which could have wiped out the wafer-thin Parliamentary majority of the current Liberal government.
Elsewhere, Chinese individuals abroad may still be kept under close surveillance:
"Stalking of expat dissidents is facilitated by digital technology. Activity on Facebook (a website blocked in China) is monitored, but it doesn’t stop there. Western governments have shown unbelievable lack of caution in giving contracts to Chinese firms for sensitive work such as surveillance systems. Advanced internet-linked CCTV cameras with face-tracking capacity in use on the London Underground and Gatwick Airport are supplied by Hangzhou Hikvision, a company under Chinese state control. Potentially the data may be sent to Chinese servers, allowing agents to track people wherever they go, recording them visiting church or holding a copy of Epoch Times."
