Michael Pillsbury, a China analyst who has worked as an outside adviser to Trump, told Reuters he believed the president was concerned that China not only wanted to re-negotiate the Phase 1 deal, but also had not been meeting goals in purchasing from United States.

“There is no specific agreement for a phased rollback of the tariffs,” said Michael Pillsbury, an outside adviser to Trump.

“The biggest accomplishment on the trade talks is getting them (China) back to the table, but there’s no date set and there was no public mention ... that they have taken back any of the ‘reneging,’” said Michael Pillsbury, an outside trade adviser to Trump, adding the concessions were worth it to get talks started.
