U.S. and Chinese officials began a second day of talks in Stockholm on Tuesday to resolve longstanding economic disputes and step back from an escalating trade war between the world's two biggest economies.

Beijing's top trade official says China and the United States have agreed to work on extending a deadline for new tariffs on each other after two days of trade talks in Stockholm

The Stockholm meeting, following similar talks in Geneva and London, is set to extend a 90-day pause on those tariffs. During the hiatus, U.S. tariffs have been lowered to 30% on Chinese goods, and China set a 10% tariff on U.S. products.
