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 denied President Trump’s claims that talks to reduce tariffs are happening.

Amid escalating trade tensions, China is considering excluding essential U.S. products from retaliatory tariffs, particularly in healthcare and semiconductors, to mitigate supply chain disruptions. The American Chamber of Commerce in China reported that some businesses may exit China if the tariff war persists,

President Trump said that “we’re meeting with China” on tariffs, comments aimed at soothing jittery financial markets. But Chinese officials say no talks have taken place.

Beijing is going on an international charm campaign to coax other countries hit hard by “Liberation Day” tariffs to take on the U.S.
