China said on Thursday it hoped U.S. officials would bring a problem-solving attitude to renewed trade talks in advance of a meeting between Presidents Donald Trump and Xi Jinping next week in Japan. Negotiations to reach a broad trade deal broke down last month after U.S. officials accused China of backing away from previously agreed commitments. A telephone call between Trump and Xi on Tuesday, as well as confirmation the two will meet in Japan on the sidelines of a Group of 20 summit, have rekindled hopes of a detente.
