“I think both sides have a desire to reach an agreement,” Mr. Mnuchin said. “We’ve made a lot of progress.”
Among the biggest sticking points has been how the two sides would enforce any trade agreement and whether the United States would agree to remove all, or at least most, of the tariffs it placed on Chinese products.
This month, Mr. Mnuchin said substantial progress had been made on an enforcement mechanism, which would give both sides the ability to hold each other accountable if the agreement was abrogated.
Mr. Mnuchin declined to provide details of the remaining obstacles, but he said this round of talks would continue to focus on China’s longstanding practice of subsidizing its industries. He also expected the two sides to discuss Mr. Trump’s move this month to end waivers that allowed countries like China to import oil from Iran.
As part of its effort to punish Iran by tightening economic sanctions, the United States gave countries, including China, until May 1 to halt purchases of Iranian oil or face American sanctions.
China, which imports large quantities of oil from Iran, has criticized the move.
“China consistently opposes U.S. unilateral sanctions,” Geng Shuang, a Chinese Foreign Ministry spokesman, said this month.
Mr. Mnuchin said the Trump administration has made clear to China how important the effort is and has conveyed that China would face sanctions if it continued to purchase Iranian oil.
“There’s still some significant issues that are open,” he said.
