BEIJING (AP) — China says any change in U.S. policy favoring formal recognition of Taiwan will “seriously” damage peace and stability across the Taiwan Strait and undermine relations between Beijing and Washington.

The comments from the spokesman for the Cabinet’s Taiwan Affairs Office Wednesday follow President-elect Donald Trump’s remarks over the weekend that he didn’t feel “bound by a one-China policy” unless the U.S. could gain benefits from China in trade and other areas.

Under the one-China policy, the U.S. recognizes Beijing as China’s government and maintains only unofficial relations with Taiwan, which broke from the Chinese mainland in 1949.

Spokesman An Fengshan said breaching the one-China principle “will seriously affect peace and stability across the Taiwan Strait.”
