The U.S. Trade Representative's office said on Friday it was continuing to develop final determination on Section 301 tariffs on Chinese imports and will make a decision public in the coming days.

"USTR continues to develop the final determination regarding proposed modifications of the actions in the Section 301 investigation of the People’s Republic of China’s Acts, Policies, and Practices Related to Technology Transfer, Intellectual Property, and Innovation," a USTR spokesman said in a statement.

"As USTR continues this work, we expect to make the final determination public in the coming days," the spokesperson said.

The agency had previously said that it would announce a decision by the end of August.
