After two days of talks in London, the U.S. and China late Tuesday agreed on what they called a framework to get a May trade truce back on track. Investors yawned, with U.S. stock-index futures a shade lower Wednesday morning.

United States and Chinese officials said they had agreed on a framework for a trade truce, which removed China's export restrictions on rare earths.
