WASHINGTON — A day after agreeing to resume trade talks with China, President Trump and his top advisers said no timeline existed for reaching a deal and suggested that the two sides remained as far apart as they were when talks broke up in May.

The comments came as the administration continued to ease restrictions on China, removing eight companies from the Commerce Department’s blacklist and taking steps to allow Huawei, the Chinese telecommunications giant, to purchase American technology. Those steps, while welcomed by American businesses, fueled concerns among some lawmakers that Mr. Trump was giving away too much in return for vague promises from President Xi Jinping of China to buy more American goods.

“We’re moving along toward a reciprocal but a good trade deal, a fair trade deal,” Mr. Trump said of China during remarks in Seoul, South Korea, on Sunday. “And we’ll see where that goes, but we had a very, very good feelings with President Xi and myself.”

Over the weekend, Mr. Trump told Fox News that Mr. Xi “wants to make a deal. I want to make a deal. Very big deal, probably, I guess you’d say the largest deal ever made of any kind, not only trade.”
