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.”
