One-China policy reaffirmed by US

White House reassures after Trump's tweets raise concerns

President Barack Obama's administration reaffirmed the United States' one-China policy on Monday, following president-elect Donald Trump's phone call with Taiwan leader Tsai Ing-wen on Friday and his China-related tweets on Sunday.

The US is committed to the one-China policy, White House Press Secretary Josh Earnest reiterated on Monday. The policy has been in place for almost 40 years and has been aimed at promoting peace and stability in the Taiwan Straits, Earnest said.
