I once took a Chinese ambassador in London to a high-end French restaurant in the hope they would repeat Prime Minister Zhou Enlai’s much-quoted answer to Richard Nixon’s question ‘What is the impact of the French Revolution?’, to which the prime minister replied ‘It’s too soon to tell.’ Sadly this was not forthcoming, but I was treated to a stern lecture about how the full imposition of ‘what you call human rights’ in China would lead to widespread violence and death and was then asked, ‘Why do you think your values would work in a culture you don’t understand?’
