China appears to have quietly rolled back retaliatory tariffs of 125% on some semiconductors made in the United States, according to details provided to CNN on Friday by three import agencies in the southern technology hub of Shenzhen.

Levies on certain U.S.-made microchips have been dropped, importers say. Meanwhile, China has denied President Trump’s claims that talks to reduce tariffs are happening.

China is considering exempting some U.S. imports from its 125% tariffs and is asking businesses to provide lists of goods that could be eligible in the biggest sign yet that Beijing is worried about the economic fallout from its trade war with Washington.
