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.

U.S. and Chinese officials agreed to seek an extension of their 90-day tariff truce on Tuesday, following two days of what both sides described as constructive talks in Stockholm aimed at defusing an escalating trade war between the world's two biggest economies that threatens global growth.
