In the past China has lambasted the DPP. Yet Mr Zhang, who has a reputation as a poker-faced diplomat, was all twinkled-eyed geniality. At times with Ms Chen, he even broke out of Mandarin and into the native Taiwanese.

Later he claimed that China respected Taiwanese people’s choices—including, presumably, their politics. He invited Taiwanese of all political persuasions to participate in the development of cross-strait relations. That, too, was rare. With Mr Ma a lame duck, China may be preparing to hold its nose and deal with a DPP government after elections in 2016. Ms Chen’s welcome of Mr Zhang in Kaohsiung, heartland of the independence movement, also suggests a new pragmatism on the part of the DPP. It needs to persuade voters that it can manage relations with China.

Though dogged by rowdy protesters, Mr Zhang kept up cheerful appearances. It all stands in contrast to China’s rows with other Asian nations over maritime claims, as well as its denouncing of protesters in Hong Kong (see article) calling for more democracy.
