Companies ranging from retailers to electronics firms have made submissions to the US trade department warning that more tariffs will hurt their business and consumers.
Still, in his latest comments the US president appeared more optimistic about striking a trade deal.
“I think we have a chance. I know that China wants to make a deal. They don’t like the tariffs, and a lot of companies are leaving China in order to avoid the tariffs,” Mr Trump told reporters at the White House on Tuesday.
Despite moves to resume talks, recent comments from both sides suggest they still remain far apart on many issues.
Sticking points in trade negotiations have included how to enforce a deal and how fast to roll back tariffs.
