U.S. negotiators are preparing to press China on long-standing demands that it reform how it treats American companies' intellectual property in order to seal a trade deal that could prevent tariffs from rising on Chinese imports.

A new round of trade talks begins in Beijing on Monday, after the most recent set of negotiations concluded in Washington a week ago without a deal and with the top U.S. negotiator declaring that a lot more work needed to be done.

A White House official said on Friday that preparations were under way and the talks would continue to focus on pressing Beijing to make structural reforms.
