Many of the debates inside the Conservative party about how western democracies should handle China are entirely common across Europe and the US, but somehow they have been conducted in a more heated and personalised way.
One reason may be the confused and slow leadership on China shown by the government, symbolised by the refusal to follow Germany in publishing a China strategy. Others blame the entrenched factionalist political culture created by Brexit, and the narcissism of small differences. But the revelations that someone under investigation for allegedly being a Chinese spy was operating at the centre of Tory debates will only make the atmosphere worse. The person in question has insisted he is completely innocent.
