In his ‘Lenin and Herrenvolk Democracy’, Losurdo makes an insightful observation on the policy of ex-colonial powers in relation to their former colonies. Hong Kong was, of course, forcefully stolen from China after the first opium war (1839-42), and then ‘returned’ with much reluctance in 1999. Losurdo writes:
Secessionist tendencies of every kind are once again lying in wait, regularly fed by the ex-colonial powers. When it wrested Hong Kong from China, Great Britain certainly did not conceive of self-determination, and it did not remember it [or bourgeois democracy for that matter] even during the long years during which it exercised its dominion. But, suddenly, on the eve of Hong Kong’s return to China, to the motherland, the governor sent by London, Chris Patten, a conservative, had a species of illumination and improvised conversion: he appealed to the inhabitants of Hong Kong to claim their right to “self-determination” against the motherland, thus remaining within the orbit of the British Empire (Lenin Reloaded, p. 249).
You can lay a certain bet that English, and indeed US, influences are at work in Hong Kong at the moment. That said, people in the rest of China say that Hong Kong has become much more Chinese over the last decade or more. That process continues.
