On Thursday evening, US President Donald Trump and Chinese President Xi Jinping (習近平) spoke for the first time since Trump’s inauguration, following a frosty period initiated by Trump’s Dec. 2 call with President Tsai Ing-wen (蔡英文). Trump’s refusal to adhere to the “one China” policy shortly after the call with Tsai was apparently the reason for Xi’s previous refusal to speak with him.
