Trump's China policy zigs and zags

Last week, Donald Trump broke 40 years of protocol when he spoke directly to the President of Taiwan.  China, which considers Taiwan a renegade province, was officially disturbed.  Today, he named his Ambassador to China: Iowa Governor Terry Branstad, and China is said to be reacting "warmly."  When Trump zigged, some called it a rookie mistake — until it turned out that Bob Dole helped set up the call with Taiwan.  Will the zag mend fences with China? We get the latest on a President-elect unrestricted by diplomatic conventions.
