US stocks were higher late on Thursday as the latest signs of progress in US-China trade relations relieved investors, though indexes pared gains after another report raised fresh worries about the outlook for a deal.
China said it had agreed with the United States to remove tariffs in phases, while state-owned Xinhua News Agency said Beijing was also considering removing restrictions on poultry imports.
But indexes pared gains in afternoon trading after a Reuters report, citing sources, said that the White House's plan to roll back China tariffs faces internal opposition and that no final decision has been made yet.
An interim US-China trade deal is expected to include a US pledge to scrap tariffs scheduled for Dec. 15.
"That's clearly the biggest driver from premarket on," said Oliver Pursche, chief market strategist of Bruderman Asset Management in New York. "The devil is in the details, but the fact that both sides - and particularly China - has said we've come to an agreement - I think that's what is giving this so much credibility."
