China warns Trump against ignoring its Taiwan interests

By Ben Blanchard BEIJING (Reuters) - China expressed "serious concern" on Monday after U.S. President-elect Donald Trump said the United States did not necessarily have to stick to its long-held stance that Taiwan is part of "one China", calling it the basis for relations. Trump's comments on "Fox News Sunday", questioning nearly four decades of U.S. policy, came after he prompted a diplomatic protest from China over his decision to accept a telephone call from Taiwan President Tsai Ing-wen on Dec. 2. China's Foreign Ministry said cooperation was "out of the question" if Washington could not recognize Beijing's core interest on Taiwan, indicating it would reject any effort by Trump to use the issue as a bargaining chip in a long list of commercial and security problems facing the two countries.
