President-elect Donald Trump's incoming White House chief of staff on Sunday played down the prospect that Trump would revisit Washington's decades-old "one China" policy, even though he suggested as much a week ago. Since 1979, the United States has acknowledged Taiwan as part of "one China" but Trump prompted a diplomatic protest from Beijing after he accepted a congratulatory phone call on his election win from President Tsai Ing-wen of Taiwan on Dec. 2. "We are not suggesting that we're revisiting 'one China' policy right now," Trump aide Reince Priebus said on "Fox News Sunday with Chris Wallace." "He is not president right now and he's respectful to the current president," Priebus said.
