President Trump’s order continues a reprieve from the threat of escalating tariffs and export controls, which rocked the global economy earlier this year.

In June, the two countries reached an agreement to ease tensions. The United States said it would pull back export restrictions on computer chip technology and ethane, a feedstock in petrochemical production. And China agreed to make it easier for U.S. firms to get access to rare earths.

The United States and China have extended a tariff truce for another 90 days, staving off triple-digit duties on each other's goods as U.S. retailers get ready to ramp up inventories ahead of the critical end-of-year holiday season.
