U.S. President-elect Donald Trump said the United States did not necessarily have to stick to its long-standing position that Taiwan is part of "one China," questioning nearly four decades of policy in a move likely to antagonize Beijing.
Trump's comments on Fox News Sunday came after he prompted a diplomatic protest from China over his decision to accept a telephone call on Dec. 2 from Taiwan's president.
"I fully understand the 'one China' policy, but I don't know why we have to be bound by a 'one China' policy unless we make a deal with China having to do with other things, including trade," Trump told Fox News.
Trump's call with President Tsai Ing-wen was the first such contact with Taiwan by a U.S. president-elect or president since President Jimmy Carter switched diplomatic recognition from Taiwan to China in 1979, acknowledging Taiwan as part of "one China."
Beijing considers Taiwan a renegade province and the subject is a sensitive one for China.
Chinese officials had no immediate reaction to Trump's remarks.
After Trump's phone conversation with Taiwan's president, the Obama administration said senior White House aides had spoken with Chinese officials to insist that Washington's "one China" policy remained intact. The administration also warned that progress made in the U.S. relationship with China could be undermined by a "flaring up" of the Taiwan issue.
Following Trump's latest comments, a White House aide said the Obama administration had no reaction beyond its previously stated policy positions.
