Actually the Chinese don’t seem too concerned...
“Beijing sought to play down the importance of the phone call, with foreign minister Wang Yi dismissing it as “just a small trick” by Taiwan.”
That, of course, wasn’t the original report. They seemed to have thought better of running around with their hair on fire. Unless, of course, the media was lying from the get-go. But I don’t think the Chinese like to be thwarted in any way.
