A few weeks ago, Xia Baolong, the head of China’s Hong Kong and Macau Affairs Office, called on the people of Hong Kong to vote in the legislative elections on 19 December. ‘It’s not just a vote for their preferred candidates,’ he said, ‘but also a vote of confidence in “one country, two systems”’ – the formula devised in the 1980s that was supposed to guarantee Hong Kong’s autonomy after it returned to Chinese sovereignty in 1997. On Sunday, the majority of the electorate rejected Xia’s invitation. Only 1.35 million people – 30 per cent – turned out to vote.
