According to a report by the SCMP
The report cites three people with knowledge of the talks and said that "many problems remained and that both sides still saw big gaps in structural issues such as technology transfers and enforcement mechanisms".
I wouldn't say that this comes as too much of a surprise considering the lack of details we've been getting since negotiations concluded last week. Despite the need to resolve the issues above, the report notes that Beijing is choosing to make preparations for a Trump-Xi summit as its top priority still.
As mentioned before, I reckon we could see some form of soft arrangement on trade between Trump and Xi in a couple of weeks. That will help to give markets some relief but the details are likely to be unconvincing of any real progress to ease tensions between the two countries on more pressing issues that Trump is unhappy with such as intellectual property protection and China's currency.
