(Agence France-Presse) China protested to Washington Saturday after US President-elect Donald Trump broke with decades of foreign policy and spoke with the president of Taiwan.

It was not immediately clear whether Trump’s telephone call with Tsai Ing-wen marked a deliberate pivot away from Washington’s official “One China” stance, but it fuelled fears he is improvising on international affairs.

China regards self-ruling Taiwan as part of its own territory awaiting reunification under Beijing’s rule, and any US move that would imply support for independence would likely trigger fury.

During Friday’s discussion, Trump and Tsai noted “the close economic, political and security ties” between Taiwan and the United States, according to the president-elect’s office.
