U.S. President Donald Trump said on Friday that Chinese President Xi Jinping had agreed to restart the flow of rare earth minerals and magnets to the United States.

But there was a discrepancy in the two sides’ statements after the Trump-Xi call on one of the most contentious issues: rare earths, which are needed to make all kinds of advanced technologies and are produced almost entirely in China.

President Trump says he had a "very good" phone call with Chinese President Xi Jinping yesterday and says trade talks with China will continue. Former U.S. Ambassador to China Gary Locke joins Ana Cabrera to provide more insight on the negotiations.
