President Donald Trump on Friday said he has not agreed to rollbacks of U.S. tariffs sought by China, sparking fresh doubts about when the world’s two largest economies may end a 16-month trade war that has slowed global growth.

Officials from both countries on Thursday said China and the United States had agreed to roll back tariffs on each others’ goods in a “phase one” trade deal. But the idea of tariff rollbacks met with stiff opposition within the Trump administration, Reuters reported later on Thursday.
