The top US trade negotiator suggests that the US and China are nearing an agreement that would end their trade conflict, but wouldn't commit to a specific time frame.
"Our hope is that we are in the final weeks of having an agreement," US Trade Representative Robert Lighthizer told the Senate Finance Committee Tuesday.
But there are still major issues that need to be resolved, he said.
"I can't predict success at this point."
But Trump also said Friday, "If this isn't a great deal, I won't make a deal."
