Though he has almost no China background, Jared Kushner, Mr Trump’s son-in-law, is leading the US preparation for next week’s meeting. His counterpart is Cui Tiankai, China’s ambassador in Washington. That, alone, gives China an edge. Mr Cui is a professional diplomat who knows America well — he did his postgraduate studies in the US capital and worked as an interpreter at the UN.

Mr Kushner’s chief qualification is that he is married to the president’s daughter. Mr Cui has just one job — US-China relations. Among other things, Mr Kushner is the White House point person for Middle East peace, criminal justice reform and US business innovation.

China seems to have grasped that the best way to influence Mr Trump is via his family. Chinese diplomats have gone out of their way to court Mr Kushner and Ivanka Trump, who were their guests of honour at the Chinese new year celebration in February. China has also looked favourably on Mr Trump’s business.
