The current state of the Sino-US negotiations is the first "ice-breaking" after Trump imposed a large number of tariffs on China on April 2. Regardless of whether the two sides have confirmed that they will communicate by phone or even send officials to talk privately, this is the first time that they have met publicly in a formal setting to discuss the tariff issue. Therefore, as the biggest conflicting party in the world and Trump's tariffs this time, the difficulty of Sino-US trade negotiations can be imagined. Trump is not unprepared.
