U.S. President Donald Trump asserted in an interview published Friday that tariff negotiations were underway with China, but Beijing denied any talks were taking place, the latest in a series of conflicting signals over what progress was being made to de-escalate a trade war threatening to sap global growth.

President Donald Trump said Chinese President Xi Jinping had called him, and there are active talks to strike a trade deal, according to Time. But a Chinese official has denied that any such talks are happening.

President Trump said that “we’re meeting with China” on tariffs, comments aimed at soothing jittery financial markets. But Chinese officials say no talks have taken place.
