White House economic adviser Larry Kudlow on Monday said it was possible U.S. and Chinese trade negotiators could make progress when they meet in Washington this week, and said Washington was open to looking at what proposals Beijing brought.

"Recently some of the statements coming out of Beijing have been a little more positive. They're been in the market buying some agriculture commodities from the U.S. - soybeans, pork and wheat and other things. That's a good sign," he said in a Fox News interview.

"It is possible that some additional progress will be made with China toward the end of the week," he said.

“We are open to a number of ideas, some may be short term, some may be long term,” Kudlow later told reporters outside the White House on Monday. “It’s essential that the structural issues that we've talked about for two years since I’ve been around … that stuff’s gotta get solved.”

Kudlow added that Chinese negotiators have been a “little more cooperative recently” as they have recently purchased U.S. agricultural products like soybeans, pork and wheat.
