Donald Trump and Vice President Mike Pence

President-elect Donald Trump's phone conversation with Taiwan's president was not intended to show a shift in U.S. policy on China, Vice President-elect Mike Pence said on Sunday, describing the chat as a "courtesy" call.

Trump's call with Taiwan President Tsai Ing-wen on Friday raised Chinese hackles because it was the first by a U.S. president-elect or president with a Taiwanese leader since President Jimmy Carter switched diplomatic recognition to China from Taiwan in 1979, acknowledging Taiwan as part of "one China."
